John 7:37

Let - To hinder or obstruct.

In the last day, that great day of the feast - This was the eighth day, and was called the great day, because of certain traditional observances, and not on account of any excellence which it derived from the original institution. On the seven days they professed to offer sacrifices for the seventy nations of the earth, but on the eighth day they offered sacrifices for Israel; therefore the eighth day was more highly esteemed than any of the others. It is probably to this that the evangelist refers when he calls the last day the great day of the feast. See the account of the feast of tabernacles, in the note on John 7:2 (note). It was probably when they went to draw water from the pool Siloam, and while they were pouring it out at the foot of the altar, that our Lord spoke these words; for, as that ceremony pointed out the gracious influences of the Holy Spirit, our Lord, who was the fountain whence it was to proceed, called the people to himself, that, by believing on him, they might be made partakers of that inestimable benefit.

In the last day - The eighth day of the festival.

That great day - The day of the holy convocation or solemn assembly, Leviticus 23:36. This seems to have been called the great day:

1. because of the solemn assembly, and because it was the closing scene.

2. because, according to their traditions, on the previous days they offered sacrifices for the pagan nations as well as for themselves, but on this day for the Jews only (Lightfoot).

3. because on this day they abstained from all servile labor Leviticus 23:39, and regarded it as a holy day.

4. On this day they finished the reading of the law, which they commenced at the beginning of the feast.

5. because on this day probably occurred the ceremony of drawing water from the pool of Siloam.

On the last day of the feast it was customary to perform a solemn ceremony in this manner: The priest filled a golden vial with water from the fount of Siloam (see the notes at John 9:7), which was borne with great solemnity, attended with the clangor of trumpets, through the gate of the temple, and being mixed with wine, was poured on the sacrifice on the altar. What was the origin of this custom is unknown. Some suppose, and not improbably, that it arose from an improper understanding of the passage in Isaiah 12:3; "With joy shall ye draw water out of the wells of salvation." It is certain that no such ceremony is commanded by Moses. It is supposed to be probable that Jesus stood and cried while they were performing this ceremony, that he might:

1. illustrate the nature of his doctrine by this; and,

2. call off their attention from a rite that was uncommanded, and that could not confer eternal life.

Jesus stood - In the temple, in the midst of thousands of the people.

If any man thirst - Spiritually. If any man feels his need of salvation. See John 4:13-14; Matthew 5:6; Revelation 22:17. The invitation is full and free to all.

Let him come unto me ... - Instead of depending on this ceremony of drawing water let him come to me, the Messiah, and he shall find an ever-abundant supply for all the wants of his soul.

7:37 On the last, the great day of the feast - On this day there was the greatest concourse of people, and they were then wont to fetch water from the fountain of Siloam, which the priests poured out on the great altar, singing one to an other, With joy shall ye draw water from the wells of salvation. On this day likewise they commemorated God's miraculously giving water out of the rock, and offered up solemn prayers for seasonable rains.
