37 On the final and climactic day of the Feast, Jesus took his stand. He cried out, "If anyone thirsts, let him come to me and drink. 38 Rivers of living water will brim and spill out of the depths of anyone who believes in me this way, just as the Scripture says." 39 (He said this in regard to the Spirit, whom those who believed in him were about to receive. The Spirit had not yet been given because Jesus had not yet been glorified.)
40 Those in the crowd who heard these words were saying, "This has to be the Prophet." 41 Others said, "He is the Messiah!" But others were saying, "The Messiah doesn't come from Galilee, does he? 42 Don't the Scriptures tell us that the Messiah comes from David's line and from Bethlehem, David's village?" 43 So there was a split in the crowd over him. 44 Some went so far as wanting to arrest him, but no one laid a hand on him.

Commentary on John 7:37-39
(Read John 7:37-39)
On the last day of the feast of tabernacles, the Jews drew water and poured it out before the Lord. It is supposed that Christ alluded to this. If any man desires to be truly and for ever happy, let him apply to Christ, and be ruled by him. This thirst means strong desires after spiritual blessings, which nothing else can satisfy; so the sanctifying and comforting influences of the Holy Spirit, were intended by the waters which Jesus called on them to come to Him and drink. The comfort flows plentifully and constantly as a river; strong as a stream to bear down the opposition of doubts and fears. There is a fulness in Christ, of grace for grace. The Spirit dwelling and working in believers, is as a fountain of living, running water, out of which plentiful streams flow, cooling and cleansing as water. The miraculous gifts of the Holy Spirit we do not expect, but for his more common and more valuable influences we may apply. These streams have flowed from our glorified Redeemer, down to this age, and to the remote corners of the earth. May we be anxious to make them known to others.
Commentary on John 7:40-53
(Read John 7:40-53)
The malice of Christ's enemies is always against reason, and sometimes the staying of it cannot be accounted for. Never any man spake with that wisdom, and power, and grace, that convincing clearness, and that sweetness, wherewith Christ spake. Alas, that many, who are for a time restrained, and who speak highly of the word of Jesus, speedily lose their convictions, and go on in their sins! People are foolishly swayed by outward motives in matters of eternal moment, are willing even to be damned for fashion's sake. As the wisdom of God often chooses things which men despise, so the folly of men commonly despises those whom God has chosen. The Lord brings forward his weak and timid disciples, and sometimes uses them to defeat the designs of his enemies.
