Exodus 10:7-9

7Pharaoh’s officials now came to Pharaoh and appealed to him. “How long will you let this man hold us hostage? Let the men go to worship the Lord their God! Don’t you realize that Egypt lies in ruins?”

8So Moses and Aaron were brought back to Pharaoh. “All right,” he told them, “go and worship the Lord your God. But who exactly will be going with you?”

9Moses replied, “We will all go—young and old, our sons and daughters, and our flocks and herds. We must all join together in celebrating a festival to the Lord.”
