37 On the last day of the feast, the great day, Jesus stood up and proclaimed, "If any one thirst, let him come to me and drink. 38 He who believes in me, as the scripture has said, 'Out of his heart shall flow rivers of living water.'" 39 Now this he said about the Spirit, which those who believed in him were to receive; for as yet the Spirit had not been given, because Jesus was not yet glorified.
40 When they heard these words, some of the people said, "This is really the prophet." 41 Others said, "This is the Christ." But some said, "Is the Christ to come from Galilee? 42 Has not the scripture said that the Christ is descended from David, and comes from Bethlehem, the village where David was?" 43 So there was a division among the people over him. 44 Some of them wanted to arrest him, but no one laid hands 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.
