Exodus 10:8-11

So 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?” Moses 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.” Pharaoh retorted, “The LORD will certainly need to be with you if I let you take your little ones! I can see through your evil plan. Never! Only the men may go and worship the LORD, since that is what you requested.” And Pharaoh threw them out of the palace.
