Exodus 10:7-10

And Pharaoh's servants said to him, How long shall this man be a snare to us? Let the men go, that they may serve the Lord their God; do you not yet understand and know that Egypt is destroyed? So Moses and Aaron were brought again to Pharaoh; and he said to them, Go, serve the Lord your God; but just who are to go? And Moses said, We will go with our young and our old, with our sons and our daughters, with our flocks and our herds [all of us and all we have], for we must hold a feast to the Lord. Pharaoh said to them, Let the Lord be with you, if I ever let you go with your little ones! See, you have some evil purpose in mind.
