Exodus 8:26-28

Amplified Bible

²⁶ But Moses said, “It is not right [or even possible] to do that, for we will sacrifice to the Lord our God what is repulsive and unacceptable to the Egyptians [that is, animals that the Egyptians consider sacred]. If we sacrifice what is repulsive and unacceptable to the Egyptians, will they not riot and stone us? ²⁷ We must go a three days’ journey into the wilderness and sacrifice to the Lord our God as He commands us.” ²⁸ So Pharaoh said, “I will let you go, so that you may sacrifice to the Lord your God in the wilderness; only you shall not go very far away. Plead [with your God] for me.”
