John 7:29

“But I know him, etc.] His nature and perfections, his purposes and promises, his council and covenant, his mind and will; and indeed none knows him but he, and those to whom he pleases to reveal him; and there is good reason why he should have intimate and perfect knowledge of him: for I am from him; being the only begotten of him, and as such lay in his bosom, and knew him, and his whole heart, and was privy to all of him, and that that is within him; and he hath sent me; in an office capacity to redeem his people. This is the original descent of Christ, which the Jews knew not, though they pretended to know him, and whence he was.”

“l am from him - By eternal generation: and he hath sent me - His mission follows from his generation. These two points answer those: Do ye know me? Do ye know whence I am? John 7:30”

“7:29 I come from him: Jesus sidestepped the speculation (7:27, 40-44) about his earthly origins and focused on his heavenly origins. His astounding claim provoked the religious leaders to try to arrest him for blasphemy (7:30; cp. 10:30-33).”

“I: Joh 1:18, Joh 8:55, Joh 10:15, Joh 17:25, Joh 17:26 for: Joh 3:16, Joh 3:17, Joh 13:3, Joh 16:27, Joh 16:28, Joh 17:18; Jo1 1:2, Jo1 4:9, Jo1 4:14 John 7:30”
