Exodus 10:8-11 ESV
So Moses and Aaron were brought back to Pharaoh. And he said to them, “Go, serve the LORD your God. But which ones are to go?” Moses said, “We will go with our young and our old. We will go with our sons and daughters and with our flocks and herds, for we must hold a feast to the LORD.” But he said to them, “The LORD be with you, if ever I let you and your little ones go! Look, you have some evil purpose in mind. No! Go, the men among you, and serve the LORD, for that is what you are asking.” And they were driven out from Pharaoh’s presence.
