Exodus 8:25-27

Pharaoh called in Moses and Aaron and said, “Go ahead. Sacrifice to your God—but do it here in this country.” Moses said, “That would not be wise. What we sacrifice to our GOD would give great offense to Egyptians. If we openly sacrifice what is so deeply offensive to Egyptians, they’ll kill us. Let us go three days’ journey into the wilderness and sacrifice to our GOD, just as he instructed us.”
