A Tough Time to be Alive

Our #7 biblically significant discovery in archaeology takes us back again to the time of the #10 discovery. If you haven’t read about the Assyrian Lachish Reliefs please click here to become more familiar with the events of 8th century BC Judah.

The year is 701BC. Sennacherib, the King of Assyria, has destroyed nearly every prominent town in the southern kingdom of Judah. Israel lies in ruins. Sennacherib thrusts the power of the Assyrian army toward the all-important city of Jerusalem. Jerusalem houses the God of the Jews. The defeat of Jerusalem would be a large strategic and symbolic victory.

The Assyrians employ the military strategy of the siege. The army surrounds the fortified walls of a city, cut off all water and food to the city, and then they wait. The term, “siege” derives from sedere, Latin for “to sit”. Attacking armies would wait weeks, months or even years. Assyria had recently besieged nearby Samaria, destroying it after waiting 3 years. As the people in the city grew sick and weak the healthy army would then advance to destroy the city. There are usually only three outcomes of a siege: survive by finding a way to get food and water, surrender or die.

Jerusalem faces certain ruin. Hezekiah, one of the few godly kings, encourages his people to trust in God. God will deliver them from Sennacherib. 2 Kings 18:7 tells us, “He rebelled against the king of Assyria and would not serve him.” In 2 Kings 18 we learn the Assyrian commander tells the people of Jerusalem, “Do not listen to Hezekiah, for he is misleading you when he says, ‘The Lord will deliver us.’ Has the god of any nation ever delivered his land from the hand of the kind of Assyria?” The Assyrians first try to convince the people of Jerusalem to overthrow Hezekiah.

The head Assyrian commander tells the people of Jerusalem, “Has my master sent me to speak these words to your master and to you, and not to the men sitting on the wall, who are doomed to with you to eat their own dung and to drink their own urine?” (2 Kings 18:27) If the people of Jerusalem don’t overthrow Hezekiah they, their wives and children will be forced to desperate measures just to stay alive.
The people of Jerusalem had a secret. They had been involved in one of the greatest engineering feats of the ancient world. It’s amazing what humans can accomplish when their backs are against the wall. The inhabitants of Jerusalem, facing certain death, found a secret way to get a constant source of water into Jerusalem. The Bible, in three areas, briefly mentions our #7 discovery:

“And the rest of the acts of Hezekiah, and all his might, and how he made a pool, and a conduit, and brought water into the city, are they not written in the book of the chronicles of the kings of Judah?” 2 Kings 20:20

“And when Hezekiah saw that Sennacherib was come, and that he was purposed to fight against Jerusalem, He took counsel with his princes and his mighty men to stop the waters of the fountains which were without the city: and they did help him. So there was gathered much people together, who stopped all the fountains, and the brook that ran through the midst of the land, saying, Why should the kings of Assyria come, and find much water?” 2 Chronicles 32:2-4

“This same Hezekiah also stopped the upper watercourse of Gihon, and brought it straight down to the west side of the city of David. And Hezekiah prospered in all his works.” 2 Chronicles 32:30

Hezekiah trusted in the supernatural power of God to deliver him AND he also employed immense hard work and ingenuity to keep his people alive. The Bible tells us he hid the Jerusalem water supply from the Assyrians and brought it underground into Jerusalem. This is all we know from Scripture.

Discovery

In 1838 American biblical scholar Edward Robinson shook up the archaeological world by discovering Hezekiah’s Tunnel. The tunnel was far more spectacular than anyone could have imagined. Two other tunnels had been dug in Israel out of soft chalky rock. The tunnel in Hazor is 82 feet long. The tunnel in Megiddo is 262 feet long. Hezekiah’s tunnel, in comparison, was dug through solid bed rock. What is the length of his tunnel? 1,750 feet!

The tunnel provides a constant stream of water through the city of Jerusalem. The tunnel takes water from the Gihon Spring and empties out at a place called the Pool of Siloam. The tunnel, surprisingly, does not follow the most direct route from the spring to the pool. The tunnel travels in an s-shape. If the tunnel was straight it would have only needed to have been 1070 feet, or 40% shorter. While the tunnel is far underground (appx 131 feet underground), the slope of the tunnel is precise. The tunnel slopes at a steady 0.6% grade. Once inside the tunnel another surprise is apparent. The head room within the tunnel varies considerably. The tunnel is always about as wide as a man’s shoulders. At the beginning of the tunnel the head room is pretty tight causing people to have to walk through it a bit hunched over. The last 160 feet of the tunnel, however, the ceiling soars up to 17 feet tall.

Toward one end of the tunnel, amazingly, an ancient Hebrew inscription was found on the wall. The inscription commemorates the point when two teams, digging from each end, finally met in the middle. The inscription reads:

“[…when] (the tunnel) was driven through. And this was the way in which it was cut through: While […] (were) still […] axe(s), each man toward his fellow, and while there were still three cubits to be cut through, [there was heard] the voice of a man calling to his fellows, for there was an overlap in the rock on the right [and on the left]. And when the tunnel was driven through, the quarrymen hewed (the rock), each man toward his fellow, axe against axe; and the water flowed from the spring toward the reservoir for 1200 cubits, and the height of the rock above the head(s) of the quarrymen was 100 cubits.”

Scientists have used several techniques to confirm the 8th century date of the tunnel. Some, especially those who claim the Jewish people did not have a sovereign kingdom in Jerusalem, claim the tunnel must have been created substantially more recent than 2,700 years ago. Analysis of the ancient writing; Carbon 14 dating of the plant life disrupted by the tunnel; uranium-thorium dating of the stalactites and stalagmites that grew after completion of the tunnel have all supported a date of around 700BC, the date given in the Bible for these events.

Construction of the Tunnel

How was Hezekiah’s Tunnel constructed without modern day equipment? How could two teams 131 feet underground, without GPS, meet in the middle connecting the two tunnels? How were the workers and subsequent users of the tunnel able to breathe oxygen? Why was the tunnel S-shaped and not straight? How were the workers able to maintain a precise 0.6% grade slope underground for 1,750 feet? These questions, ultimately, remain a mystery.

Over the past 150 years many theories have been offered to explain all these questions. Room is not available in this post to go into all of the theories. The wonder of it all is that the tunnel stands today, undisputed, still carrying water from the Gihon Spring to the Pool of Siloam.

Visiting the Tunnel Today

If you ever get the chance to visit Jerusalem I highly recommend you take the time, walk down the steep hill from the temple mount and walk through Hezekiah’s Tunnel. Most famous archaeological discoveries are only observable behind the glass of a museum. Hezekiah’s Tunnel is the equivalent of an amusement park. Many tours to Israel, unfortunately, do not include in the itinerary a walk through the tunnel. Others make the tunnel an optional part of the trip. Yes, if you are claustrophobic you might not like some of the portions of the tunnel. Yes, your feet may become numb as you walk through the cold spring water. Remember what was on the line for the people constructing the tunnel. Be successful or your friends, your parents, your kids, your wife may all be dead soon. Step into Hezekiah’s day and walk through the tunnel with the absolute awe of people who trusted in God and worked their heart out.

Significance

Hezekiah’s Tunnel brings to living color an amazing engineering feat at a desperate time in the history of Jerusalem. If the tunnel was 10 feet long and 5 feet underground it would still be a valuable discovery. The grandeur of Hezekiah’s Tunnel propels it to the front of the line. Few significant artifacts exist from the 8th century BC. The interaction we can have today with Hezekiah’s Tunnel is stunning.

      Love Love Love this series! Keep up the good work!!!

    • JRoach

      This is so fascinating. I would definitely make the walk down the tunnel. On a side note, withing the context of the Assyrian threat, God promised, through Isaiah, defeat on them.

      Then it happened that night that the angel of the LORD went out and struck 185,000 in the camp of the Assyrians; and when men rose early in the morning, behold, all of them were dead. 2 Kings 19:35

      Tim,

      Will you be covering the Ebla tablets? I just recently learned that some of the claims made about the tablets (appearance of certain Biblical words/people) turned out to be false. I would love to get your perspective on this (now if you won’t be covering it, or later if you will be). Thanks!

      Tim:
      I can’t tell you how much I am enjoying this series! I have always had an interest in Biblical Archaeology, and I keep trying to guess which items will make your top 10 list with so many to choose from. So far, I definitely haven’t been disappointed – great job! I can hardly wait for your next installment.

      We were just in Israel for a 2nd time, and had the opportunity to walk through Hezekiah’s Tunnel! It really was one of the highlights of our trip… it wasn’t even offered on our 1st trip.

    • Christina Chi

      In March 2012, my husband and I joined a Holy Land study tour and got a chance to walk through the Hezekiah tunnel. It was an awesome experience indeed to witness that the Bible is extremely detailed & accurate, to think that this tunnel was only recorded in a few verses in the Old Testament! Our group of about 60 Chinese Christians from all over the wold suddenly burst into songs in several different languages but in one tune praising the Lord all along the pitch dark tunnel! Praise God!

      My wishing to walk in Hezekiah’s conduit or tunnel, what an tourist’s event. This is a excellent archaelogical confirmation of the Bible’s record, inspired by Jehovah God.
      If the Bible is truthful on actual people and real places existing. Then why not trust in the outstanding wisdom and direction the Bible provides for mankind, considering the awful condition the world of humanity is in?

      I walked through in 1989. I was 29 years old. Two young women (German and English), at the Lutheran Hostle where I was staying) asked me to accompany them to an unknown destination. It turned out to be Hezekiah’s tunnel.
      An old Palestinian man gave us candles and followed us into the tunnel. Unfortunately, he was inappropriately trying to get his jollies touching the English woman. I became tense when I realized what was happening and had no idea how far it was to the pool of Siloam end of the tunnel. When we finally made it we encountered Arab youths threatening to pelt us with stones. They relented and we ascented the steps out of the subterranean pool. I walked back to the hostel in jeans soaked by the waste high water. What an adventure!

    • Catherine

      A walk I will never forget. If you plan a Holy Land trip be sure this is on your itinerary. It is amazing.

      Re: J Roach’s Comment:

      So, god sent his personal hit squad to kill 180,000 Assyrians without his own “believers” having to break a sweat. What a guy! It seems god didn’t create all men equal. It seems if you just bent the knee you were automatically better than your opponents who now only deserved annihilation. It seems god sells his services cheap.. a few genuflections, a few burnt animals, some mumbled prayers and LO! he becometh your very own terminator. He’ll smite anyone for the right praise. Oh come let us adore him. I’ll bet he sold arms to both sides…they do say he’s wise..oh so wise. Keep him.

      Re: Stim’s Comment

      We can all tell by your snide sarcasm that you have probably never even bothered to crack open the Bible a single time in your life, so you have no clue as to the “context” of the scripture above or WHY God would do such a thing… I urge you to TRULY be the “free thinker” that you most likely think you ARE, and actually READ IT!!! It just might open your eyes, your mind and maybe even your heart to the One True GOD who created you, loves you with a jealous passion, and who desperately wants to have a personal
      relationship with you!!!

      I just spent two weeks (July 5th – our 35th wedding anniversary – to July 19th) in Israel. We took a two-week course of study at Jerusalem University College with Dr. Paul Wright (an amazing teacher). I had the privilege of walking through this tunnel from one end to the other. It was FASCINATING!!! As I walked through I wondered how these men without modern technology were able to accomplish such a feat, but I remembered that with God, all things are possible. Going through this tunnel brought the things that I had read about Hezekiah in the Scriptures to life. I will never read my Bible the same again after leaving Israel. I have walked with the Lord now for nearly 40 years, and I continue to grow in awe of Him who is God all by Himself!!! One day I will stand before Him because I have been redeemed by the precious blood of the Lord Jesus Christ and indwelt by His Spirit. Praise God!!!!!!!
