Acts: 11
2 ...when Peter was come up to Jerusalem, they that were of the circumcision contended with him,
3 Saying, Thou wentest in to men uncircumcised, and didst eat with them.
4 But Peter rehearsed the matter from the beginning, and expounded it by order unto them, saying,
5 I was in the city of Joppa praying: and in a trance I saw a vision, A certain vessel descend, as it had been a great sheet, let down from heaven by four corners; and it came even to me:
6 Upon the which when I had fastened mine eyes, I considered, and saw fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air.

Probably should have backed off whatever put him into that trance.
