And on the morrow Peter went away with them; he delays not to obey the heavenly vision; but as Abraham took his journey the very next morning after that he had received the command, Genesis 22:3, so did Peter here, and bis dat qui cito dat, he doubles his obedience that obeys speedily and cheerfully. And certain brethren from Joppa accompanied him; these brethren were six in number, as Acts 11:12; who might undertake this journey,
1. Out of respect to Peter, to accompany him.
2. Being moved at the extraordinary visions that were spoken of. But especially:
3. Disposed by the providence of God to accompany St. Peter, that they might testify the grace of God that was come unto the Gentiles, when it might be afterwards questioned.
