Exodus 12:38-40

Lexham English Bible

³⁸ And also a mixed multitude^[a] went up with them and sheep and goats and cattle, very numerous livestock. ³⁹ And they baked the dough that they had brought out from Egypt as cakes, unleavened bread, because it had no yeast when they were driven out from Egypt, and they were not able to delay, and also they had not made provisions for themselves.

⁴⁰ And the period of dwelling of the Israelites^[b] that they dwelled in Egypt was four hundred and thirty years.
