37 On the last day, the climax of the festival, Jesus stood and shouted to the crowds, "Anyone who is thirsty may come to me! 38 Anyone who believes in me may come and drink! For the Scriptures declare, 'Rivers of living water will flow from his heart.'" 39 (When he said "living water," he was speaking of the Spirit, who would be given to everyone believing in him. But the Spirit had not yet been given, because Jesus had not yet entered into his glory.)

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.
