Exodus 12:38-40

New Catholic Bible

³⁸ There was also a large crowd of people of mixed ancestry with them, together with large numbers of flocks and herds. 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.
