Exodus 12:39-41

New Catholic Bible

³⁹ They baked the dough that they had carried with them from Egypt as cakes of unleavened bread for it had not been leavened. They had been hurried out of Egypt and had not had time to hesitate nor to prepare provisions for the journey.

⁴⁰ The children of Israel had lived in Egypt for four hundred and thirty years. ⁴¹ At the end of four hundred and thirty years, exactly to the day, all the hosts of the Lord went up out of Egypt.
