Exodus 12:30-32

30And Pharaoh rose up in the night, he, and all his servants, and all the Egyptians; and there was a great cry in Egypt; for there was not a house where there was not one dead.

31And he called for Moses and Aaron by night, and said, Rise up, and get you forth from among my people, both ye and the children of Israel; and go, serve Yhwh, as ye have said. 32Also take your flocks and your herds, as ye have said, and be gone; and bless me also.
