Exodus 10:9; Exodus 10:26

9 Moses said, "We shall go with our young and our old; with our sons and our daughters, with our flocks and our herds we shall go, for we must hold a feast to the LORD ."

26 "Therefore, our livestock too shall go with us; not a hoof shall be left behind, for we shall take some of them to serve the LORD our God. And until we arrive there, we ourselves do not know with what we shall serve the LORD ."
