Exodus 10:7-9

7Pharaoh’s servants said to him, “How long will this man be a menace to us? Release the people so that they may serve the Lord their God. Do you not know that Egypt is destroyed?”

8So Moses and Aaron were brought back to Pharaoh, and he said to them, “Go, serve the Lord your God. Exactly who is going with you?”

9Moses said, “We will go with our young and our old, with our sons and our daughters, and with our sheep and our cattle we will go, because we are to hold a pilgrim feast for the Lord.”
