Exodus 12:38

35 And the children of Israel had done as Moses had said; and they got from the Egyptians ornaments of silver and of gold, and clothing:

36 And the Lord had given the people grace in the eyes of the Egyptians so that they gave them whatever was requested. So they took away all their goods from the Egyptians.

37 And the children of Israel made the journey from Rameses to Succoth; there were about six hundred thousand men on foot, as well as children.

38 And a mixed band of people went with them; and flocks and herds in great numbers.

39 And they made unleavened cakes from the paste which they had taken out of Egypt; it was not leavened, for they had been sent out of Egypt so quickly, that they had no time to make any food ready.

40 Now the children of Israel had been living in Egypt for four hundred and thirty years.

41 And at the end of four hundred and thirty years, to the very day, all the armies of the Lord went out of the land of Egypt.
