Exodus 10:24-26

Living Bible

²⁴ Then Pharaoh called for Moses and said, “Go and worship Jehovah—but let your flocks and herds stay here; you can even take your children with you.”

²⁵ “No,” Moses said, “we must take our flocks and herds for sacrifices and burnt offerings to Jehovah our God. ²⁶ Not a hoof shall be left behind; for we must have sacrifices for the Lord our God, and we do not know what he will choose until we get there.”
