In Isaiah, chapter eight, verse six, “Forasmuch as this people refuseth the waters of Shiloah that go softly,” is the first part of this theme in scripture. The ‘waters of Shiloah,” were fed by a gentle spring that served as Jerusalem’s underground source of water in times of siege by a hostile nation. They symbolized God’s gracious and gentle rule over Israel through His kindly representatives: the godly Davidic kings. Since Judah and Jerusalem were rejecting God’s beneficent rule, they would instead experience the “waters of the river, strong and many” from the region of the Euphrates: the mighty flood of invading Assyrian soldiers, as in verses seven through ten.
In the New Testament, the “waters of Shiloah,” known as the pool of Siloam in John nine, verse seven, “And said unto him, Go, wash in the pool of Siloam, (which is by interpretation, Sent.) He went his way therefore, and washed, and came seeing.” The pool of Siloam in John nine, verses one to seven, is where Jesus heals the man born blind. The significance of the “waters of Shiloah” is a blind man who received sight, went and washed according to the Son of God, after following instructions. God, through His Son, Jesus, used the water from the “pool of Siloam” to complete the healing process for that man.
“The neighbours therefore, and they, before had seen him that he was blind, said, Is not this he that sat and begged? Some said, This is he: others said, He is like him: but he said, I am he. Therefore, said they unto him, How were thine eyes opened? He answered and said, A man that is called Jesus made clay, and anointed mine eyes, and said unto me, Go to the pool of Siloam, and wash: and I went and washed, and I received sight.
