This occurred on the day after the seventh day. It's curious that each day unto the seventh, the number of bullocks is reduced...starting at 13 on the first day.

Also 7 times 2 of course totals to 14.

The total bullocks saraficed through the seventh day is 70, plus the 14 rams and 98 lambs.

Num 29:32 And on the seventh day seven bullocks, two rams, and fourteen lambs of the first year without blemish:

Num 29:33 And their meat offering and their drink offerings for the bullocks, for the rams, and for the lambs, shall be according to their number, after the manner:

Num 29:34 And one goat for a sin offering; beside the continual burnt offering, his meat offering, and his drink offering.

On the final day the eighth....

Num 29:35 On the eighth day ye shall have a solemn assembly: ye shall do no servile work therein:

Num 29:36 But ye shall offer a burnt offering, a sacrifice made by fire, of a sweet savour unto the LORD: one bullock, one ram, seven lambs of the first year without blemish:

Num 29:37 Their meat offering and their drink offerings for the bullock, for the ram, and for the lambs, shall be according to their number, after the manner:

Num 29:38 And one goat for a sin offering; beside the continual burnt offering, and his meat offering, and his drink offering.

Num 29:39 These things ye shall do unto the LORD in your set feasts, beside your vows, and your freewill offerings, for your burnt offerings, and for your meat offerings, and for your drink offerings, and for your peace offerings.

Num 29:40 And Moses told the children of Israel according to all that the LORD commanded Moses.

Again this is the day Jesus taught...

Joh 7:37 In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink.

Joh 7:38 He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.

Joh 7:39 (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)

Joh 7:40 Many of the people therefore, when they heard this saying, said, Of a truth this is the Prophet.

Joh 7:41 Others said, This is the Christ. But some said, Shall Christ come out of Galilee?

Joh 7:42 Hath not the scripture said, That Christ cometh of the seed of David, and out of the town of Bethlehem, where David was?

Joh 7:43 So there was a division among the people because of him.

John 7:37 Gill

In the last day, that great day of the feast,.... That is, of tabernacles, as appears from Joh 7:2, which was usually called חג, "the feast", in distinction from the passover and Pentecost (q); and the eighth day of it was called הרגל האחרון, "the last day of the feast" (r), as here: and it was a "great day", being, as is said in Lev 23:36, an holy convocation, a solemn assembly, in which no servile work was done, and in which an offering was made by fire unto the Lord. According to the traditions of the Jews, fewer sacrifices were offered on this day than on the rest; for on the first day they offered thirteen bullocks, and lessened one every day; so that on the seventh, day, there was but seven offered, and on the eighth day but one, when the priests returned to their lots, as at other feasts (s); but notwithstanding the Jews make out this to be the greater day for them, since the seventy bullocks offered on the other seven days, were for the seventy nations of the world; but the one bullock, on the eighth day, was peculiarly for the people of Israel (t): and besides, they observe, that there were several things peculiar on this day, as different from the rest; as the casting of lots, the benediction by itself, a feast by itself, an offering by itself, a song by itself, and a blessing by itself (u): and on this day they had also the ceremony of drawing and pouring water, attended with the usual rejoicings as on other days; the account of which is this (w):

"the pouring out of water was after this manner; a golden pot, which held three logs, was tilled out of Siloah, and when they came to the water gate, they blew (their trumpets) and shouted, and blew; (then a priest) went up by the ascent of the altar, and turned to the left hand, (where) were two silver basins--that on the west side was filled with water, and that on the east with wine; he poured the basin of water into that of wine, and that of wine into that of water.''

At which time there were great rejoicing, piping, and dancing, by the most religious and sober people among the Jews; insomuch that it is said (x), that

"he that never saw the rejoicing of the place of drawing of water, never saw any rejoicing in his life.''

And this ceremony, they say (y), is a tradition of Moses from Mount Sinai, and refers to some secret and mysterious things; yea, they plainly say, that it has respect to the pouring forth of the Holy Ghost (z).

"Says R. Joshua ben Levi, why is its name called the place of drawing water? because, from thenceשואבים רוח הקודש, "they draw the Holy Ghost", as it is said, "and ye shall draw water with joy out of the wells of salvation", Isa 12:3.''

Moreover, it was on this day they prayed for the rains for the year ensuing: it is asked (a),

"from what time do they make mention of the powers of the rains (which descend by the power of God)? R. Eliezer says, from the first good day of the feast (of tabernacles); R. Joshua says, from the last good day of the feast.--They do not pray for the rains, but near the rains;''

that is, the time of rains; and which, one of their commentators says (b), is the eighth day of the feast of tabernacles; for from the feast of tabernacles, thenceforward is the time of rains. The Jews have a notion, that at this feast the rains of the ensuing year were fixed: hence they say (c), that

"at the feast of tabernacles judgment is made concerning the waters;''

or a decree or determination is made concerning them by God. Upon which the Gemara (d) has these words,

"wherefore does the law say pour out water on the feast of tabernacles? Says the holy blessed God, pour out water before me, that the rains of the year may be blessed unto you.''

Now when all these things are considered, it will easily be seen with what pertinency our Lord expresses himself on this day, with respect to the effusion of the gifts and graces of the Spirit of God, as follows:

Jesus stood and cried; he now stood up, whereas at other times he used to sit, and spoke with a loud voice, both to show his fervour and earnestness, and that all might hear:

saying, if any man thirst, let him come to me and drink. This is to be understood not of a natural thirst, though the allusion is to it, which is very painful and distressing; as the instances of the Israelites in the wilderness, Samson after he had slain the Philistines, and our Lord upon the cross, show; much less a sinful thirst, a thirst after the riches, honours, and pleasures of this life; but a spiritual thirst, or a thirst after spiritual things, after salvation by Christ, and a view of interest in it, free and full pardon of sin through him, justification by his righteousness, a greater degree of knowledge of him, more communion with him, and conformity to him, and after the sincere milk of the word, and the breasts of Gospel ordinances: and such that thirst after these things, and eagerly desire them, and are in pain and uneasiness without them, as a man is, who has a violent thirst upon him, are such as are regenerated and quickened by the Spirit of God, and are made sensible of themselves, and of their state and condition by nature.

Now these Christ invites to come unto him, not to Moses and his law, moral or ceremonial, and to obedience to them, and works of righteousness done by them, to any creature, or creature acts; for these are cisterns without water, where no true peace, joy, righteousness, and salvation are to be had; but to himself, who is the fountain of gardens, the well of living waters, and who is as rivers of water in a dry land, to thirsty souls: and when come to him, which is by believing in him, they are encouraged to drink; that is, to take of the water of life freely, or to take of his grace freely; salvation by him is of free grace, and the pardon of sin is according to the riches of grace, and justification is freely by his grace, and so all other blessings; and of this they may drink abundantly, or they may partake of it largely: there is a fulness of grace in Christ, and there is an abundance of it communicated to his people; it is exceeding abundant; it flows, and overflows, and may be drank of to satisfaction, till their souls are as a watered garden, and they are satisfied with the goodness of the Lord.
