Exodus 12:39-41

International Standard Version

³⁹ They baked the dough that they brought out of Egypt into thin cakes of unleavened bread. It had not been leavened because they were driven out of Egypt and could not wait, nor had they prepared provisions for themselves.

⁴⁰ Now the time that the Israelis lived in Egypt was 430 years. ⁴¹ At the end of 430 years, to the very day, all the tribal divisions of the Lord went out from the land of Egypt.
