And there was a water pool named after this promise (shaw-lakh) to remind the people that Christ will born to save us - The Spirit of the Lord God is upon me, because the Lord has anointed me to bring good news to the poor; he has sent me (shaw-lakh) to bind up the brokenhearted, to proclaim liberty to the captives,  and the opening of the prison to those who are bound; to proclaim the year of the Lord's favor, and the day of vengeance of our God; to comfort all who mourn; to grant to those who mourn in Zion, to give them a beautiful headdress instead of ashes, the oil of gladness instead of mourning, the garment of praise instead of a faint spirit; that they may be called oaks of righteousness, the planting of the Lord, that he may be glorified - Isaiah 61:1-3

Once Jesus Christ read the promise in the Temple, and now he sent the blind man to the pool of Siloam(shaw-lakh) so that the people could understand the Messiah, and the Blind man became a first person to Acknowledge in the Temple that Jesus Christ is our Savior - As he passed by, he saw a man blind from birth. And his disciples asked him, Rabbi, who sinned, this man or his parents, that he was born blind? Jesus answered, It was not that this man sinned, or his parents, but that the works of God might be displayed in him. We must work the works of him who sent me while it is day; night is coming, when no one can work. As long as I am in the world, I am the light of the world. Having said these things, he spit on the ground and made mud with the saliva. Then he anointed the man's eyes with the mud and said to him, Go, wash in the pool of Siloam, which means Sent (shaw-lakh). So he went and washed and came back seeing - John 9:1-7
