Exodus 10:23-25

Amplified Bible

²³ The Egyptians could not see one another, nor did anyone leave his place for three days, but all the Israelites had [supernatural] light in their dwellings. ²⁴ Then Pharaoh called to Moses, and said, “Go, serve the Lord; only your flocks and your herds must be left behind. Even your children may go with you.” ²⁵ But Moses said, “You must also let us have sacrifices and burnt offerings, so that we may sacrifice them to the Lord our God.
