Exodus 12:37

The people took their dough before it was leavened, their kneading troughs being bound up in their clothes on their shoulders.

The children of Israel did according to the word of Moses; and they asked of the Egyptians jewels of silver, and jewels of gold, and clothing.

The LORD gave the people favor in the sight of the Egyptians, so that they let them have what they asked. They plundered the Egyptians.

A mixed multitude went up also with them, with flocks, herds, and even very much livestock.

They baked unleavened cakes of the dough which they brought out of Egypt; for it wasn’t leavened, because they were thrust out of Egypt, and couldn’t wait, and they had not prepared any food for themselves.

Now the time that the children of Israel lived in Egypt was four hundred thirty years.
