Exodus 8:25-28

Pharaoh called for Moses and Aaron and said, “Go, sacrifice to your God within the land.” But Moses said, “It is not right to do so, for we will sacrifice to the LORD our God what is an abomination to the Egyptians. If we sacrifice what is an abomination to the Egyptians before their eyes, will they not then stone us? We must go a three days’ journey into the wilderness and sacrifice to the LORD our God as He commands us.” Pharaoh said, “I will let you go, that you may sacrifice to the LORD your God in the wilderness; only you shall not go very far away. Make supplication for me.”
