Numbers 29:35
eighth day: Though this day was properly a distinct festival, and esteemed the chief or high day of the feast, yet fewer sacrifices are appointed for it than for any of the foregoing seven. On every one of them two rams and fourteen lambs were offered; but on this day there were but half as many; and whereas seven bullocks were the fewest that were offered on any of those days, on this there was only one. At this feast, there was an extraordinary ceremony of which the rabbins inform us, namely, the drawing water out of the pool of Siloam, and pouring it, mixed with wine, on the sacrifice as it lay on the altar. This they are said to have done with such expressions of joy, that it became a common proverb, "He that never saw the rejoicing of drawing of water, never saw rejoicing in all his life." The Jews pretend to ground this custom on the following passage of Isaiah - Isa 12:3, "With joy shall ye draw water out of the wells of salvation;" and to this ceremony Jesus is supposed to refer, when "in the last day, the great day of the feast, he stood and cried, saying, If any man thirst, let him come unto me, and drink: he that believeth on me, as the Scripture saith, out of his belly shall flow rivers of living water" - Joh 7:37, Joh 7:38, thereby calling off the people from their carnal mirth and festive and pompous ceremonies, to seek spiritual refreshment for their minds.
