It was on the last day of the feast that our Lord made the most explicit revelation of Himself to the people. For seven days the people dwelt in their booths; on the eighth day they celebrated their entrance into the promised land, forsook their booths, and, as it is said in the end of the chapter, “went every man to his own _house_.” But on this great day of the feast no water was drawn from the pool of Siloam. On each of the preceding days the golden pitcher was in request, and the procession that followed the priest who carried it praised God who had brought water out of the rock in the desert; but on the eighth day, commemorating their entrance into “a land of springs of water,” this rite of drawing the water ceased.
But the true worshippers among these Israelites had been seeing a spiritual meaning in the water, and had been conscious of an uneasy feeling of thirst still in the midst of these Temple services—an uneasy questioning whether even yet Israel had passed the thirsty desert, and had received the full gift God had meant to give. There were thinking men and thirsty souls then as there are now; and to these, who stood perhaps a little aside, and looked half in compassion, half in envy, at the merry-making of the rest, it seemed a significant fact that, in the Temple itself, with all its grandeur and skilful appliances, there was yet no living fountain to quench the thirst of men—a significant fact that to find water the priest had to go outside the gorgeous Temple to the modest “waters of Siloah that go softly.” All through the feast these men wondered morning by morning when the words of Joel were to come true, when it should come to pass that “a fountain should come forth of the house of the Lord,” or when that great and deep river should begin to flow which Ezekiel saw in vision issuing from the threshold of the Lord’s house, and waxing deeper and wider as it flowed. And now once more the last day of the feast had come, the water was no longer drawn, and yet no fountain had burst up in the Temple itself, their souls were yet perplexed, unsatisfied, craving, athirst, when suddenly, as if in answer to their half-formed thoughts and longings, a clear, assured, authoritative voice passed through their ear to their inmost soul: “If any man thirst, let him come unto Me and drink. He that believeth on Me, out of his belly shall flow rivers of living water.”
