Boyd’s Bible Dictionary:
(sent). (1) The celebrated pool, or tank, at Jerusalem, on the south side, near the opening of the Tyrophean valley into the Kidron valley. Originally a part of the water supply of the city (Neh. 3:1515But the gate of the fountain repaired Shallun the son of Col-hozeh, the ruler of part of Mizpah; he built it, and covered it, and set up the doors thereof, the locks thereof, and the bars thereof, and the wall of the pool of Siloah by the king's garden, and unto the stairs that go down from the city of David. (Nehemiah 3:15); Isa. 8:66Forasmuch as this people refuseth the waters of Shiloah that go softly, and rejoice in Rezin and Remaliah's son; (Isaiah 8:6); John 9:7-117And 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. 8The neighbors therefore, and they which before had seen him that he was blind, said, Is not this he that sat and begged? 9Some said, This is he: others said, He is like him: but he said, I am he. 10Therefore said they unto him, How were thine eyes opened? 11He 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. (John 9:7‑11)). (2) An Unlocated tower whose fall killed eighteen men (Luke 13:44Or those eighteen, upon whom the tower in Siloam fell, and slew them, think ye that they were sinners above all men that dwelt in Jerusalem? (Luke 13:4)). Siloam still retains its ancient name under the form of the Arabic Silwan. It is partly hewn from rock and partly built with masonry. A flight of steps leads down to it. It is no longer a natural spring of fresh, limpid water, but is fed from the Fountain of the Virgin through a rock tunnel over 1700 feet in length. The waters are brackish and colored, and the walls and steps in ruins.
Concise Bible Dictionary:
A pool on the south of Jerusalem near the west slope of the Kidron valley. It is mentioned in the Old Testament as being “by the king’s garden” when the walls of Jerusalem were being rebuilt by Nehemiah (Neh. 3:1515But the gate of the fountain repaired Shallun the son of Col-hozeh, the ruler of part of Mizpah; he built it, and covered it, and set up the doors thereof, the locks thereof, and the bars thereof, and the wall of the pool of Siloah by the king's garden, and unto the stairs that go down from the city of David. (Nehemiah 3:15)). In Isaiah 8:66Forasmuch as this people refuseth the waters of Shiloah that go softly, and rejoice in Rezin and Remaliah's son; (Isaiah 8:6), under the name of SHILOAH, it is used symbolically: the people refused its waters that went softly, preferring Syria and the king of Israel: the strong waters of Assyria should sweep them away. In the New Testament the man born blind, after being anointed with clay, was sent to wash at Siloam, which signifies “sent.” Christ being the Sent One, we are figuratively taught that light comes when Christ in humiliation is known as the Sent One of God (John 9:7,117And 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. (John 9:7)
11He 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. (John 9:11)).
The pool still exists under the name of the Birket Silwan. It is supplied with water from a fountain higher up the hill, called the Virgin’s Fountain. Several travelers have passed through the passage that connects the two, in some parts walking erect, and sometimes stooping, sometimes kneeling, and sometimes crawling on all fours. A short inscription was found at the pool, but which merely said that the passage was begun at both ends simultaneously, and met in the middle. The letters are ancient, which has led to the supposition that the passage was made in the days of Hezekiah, who made alterations in the watercourses (2 Chron. 32:3-43He 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. 4So 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 32:3‑4)). The flow of the water is intermitting, as if regulated by an underground siphon. In the winter the water rises three or four times a day, but in the summer only once in several days. The superfluous water flows in a channel cut in the rock to the gardens below. The pool is about 53 feet long, 18 feet wide, and 19 feet deep.
