Expositor's Bible Commentary Commentary John 7:29

"I know him; because I am from him, and he sent me." — John 7:29 (ASV)

His first statement may be ironic—“So you know me and where I am from, do you?” The people must have been aware of his boyhood in Nazareth and no doubt considered him to be the son of Joseph and Mary (6:42). Jesus’ reply was a renewed affirmation of his origin in God and his divine commission. His assertion evoked the dual response of belief and unbelief (cf. vv.41–44).
