John Lightfoot on John 7:38

[Out of his belly shall flow rivers of living water.] To this offering of water, perhaps, our Saviour's words may have some respect; for it was only at this feast that it was used, and none other. You have the manner of this service described in the place above quoted, to this purpose:

After what manner is this offering of water? "They filled a golden phial containing three logs out of Siloam. When they came to the water gate" [a gate of the Temple so called, as some would have it, because that water which was fetched from Siloam was brought through it], "they sounded their trumpets and sang. Then a priest goes up by the ascent of the altar, and turns to the left. There were two silver vessels, one with water, the other with wine: he pours some of the water into the wine, and some of the wine into the water, and so performs the service."

"R. Judah saith, They offer one log every of those eight days: and they say to him that offered it, 'Lift up thy hand': for upon a certain time there was one that offered it upon his feet" [Gemar. He was a Sadducee. Gloss: The Sadducees do not approve the offering of water], "and the whole congregation pelted him with their citrons. That day a horn of the altar was broke."

"Whoever hath not seen the rejoicing that was upon the drawing of this water, hath never seen any rejoicing at all."

This offering of water, they say, was a tradition given at mount Sinai: and that the prophet Jonah was inspired by the Holy Ghost upon this offering of water.

If you ask what foundation this usage hath, Rambam will tell us, "There are some kind of remote hints of it in the law. However, those that will not believe the traditional law, will not believe this article about the sacrifice of water."

I. They bring for it the authority of the prophet Isaiah, the house of drawing; for it is written, "With joy shall ye draw water," &c. Isaiah 12:3.

This rejoicing (which we have described before) they called the rejoicing of the law, or for the law: for by waters they often understand the law, Isaiah 55:1, and several other places; and from thence the rejoicing for these waters.

II. But they add moreover, that this drawing and offering of water signifies the pouring out of the Holy Spirit.

"Why do they call it the house of drawing? Because thence they draw the Holy Spirit." Gloss in Succah, ubi supr.: "In the Jerusalem Talmud it is expounded, that they draw there the Holy Spirit, for a divine breathing is upon the man through joy."

Another Gloss: "The flute also sounded for increase of the joy." Drawing of water, therefore, took its rise from the words of Isaiah: they rejoiced over the waters as a symbol and figure of the law; and they looked for the holy Spirit upon this joy of theirs.

III. But still they add further: "Why doth the law command, saying, Offer ye water on the feast of Tabernacles? The holy blessed God saith, Offer ye waters before me on the feast of Tabernacles, that the rains of the year may be blessed to you." For they had an opinion, that God, at that feast, decreed and determined on the rains that should fall the following year. Hence that in the place before mentioned, "In the feast of Tabernacles it is determined concerning the waters."

And now let us reflect upon this passage of our Saviour, "He that believeth in me, out of his belly shall flow rivers of living water." They agree with what he had said before to the Samaritan woman, chapter 4:14; and both expressions are upon the occasion of drawing of water.

The Jews acknowledge that the latter Redeemer is to procure water for them, as their former redeemer Moses had done. But as to the true meaning of this, they are very blind and ignorant, and might be better taught by the Messiah here, if they had any mind to learn.

I. Our Saviour calls them to a belief in him from their own boast and glorying in the law: and therefore I rather think those words, as the Scripture hath said, should relate to the foregoing clause, "Whosoever believeth in me, as the Scripture hath spoken about believing, Isaiah 28:16, 'I lay in Sion for a foundation a tried stone: he that believeth,' &c.: Habakkuk 2:4. 'The just shall live by his faith.'" And the Jews themselves confess, that six hundred and thirteen precepts of the law may all be reduced to this, "The just shall live by faith"; and to that of Amos 5:6, "Seek the Lord, and ye shall live."

II. Let these words, then, of our Saviour be set in opposition to this right and usage in the feast of Tabernacles of which we have been speaking: "Have you such wonderful rejoicing at drawing a little water from Siloam? He that believes in me, whole rivers of living waters shall flow out of his own belly. Do you think the waters mentioned in the prophets do signify the law? They do indeed denote the Holy Spirit, which the Messiah will dispense to those that believe in him: and do you expect the Holy Spirit from the law, or from your rejoicing in the law? The Holy Spirit is of faith, and not of the law," Galatians 3:2.
