Exodus 10:24-26

Pharaoh called in Moses: “Go and worship GOD. Leave your flocks and herds behind. But go ahead and take your children.” But Moses said, “You have to let us take our sacrificial animals and offerings with us so we can sacrifice them in worship to our GOD. Our livestock has to go with us with not a hoof left behind; they are part of the worship of our GOD. And we don’t know just what will be needed until we get there.”
