New Defender's Study Bible Notes
7:37 the last day. This phrase is referring to the final day of the eight-day annual Feast of Tabernacles (Leviticus 23:34-36; John 7:2).
7:37 come unto me. Here is still another clear affirmation by Jesus of His own deity. Only God (or a madman thinking he was God) could make such a statement as recorded here in John 7:37-38. The promise was abundantly fulfilled with the coming of the Holy Spirit after Jesus returned to the Father (Acts 2:17-21, 38-41) and His indwelling presence and guidance of believers ever since.
