Exodus 8:20-24

20Adonai did just so. A massive swarm of flies went into the house of Pharaoh and into his servant’s houses. All the land of Egypt was ruined because of the swarm of flies.

21So Pharaoh called for Moses and for Aaron and said, “Go! Sacrifice to your God—in the land.”

22But Moses said, “That would not be right. For the offerings we intend to sacrifice to Adonai our God are an abomination to the Egyptians. If we sacrifice what is an abomination to the Egyptians, wouldn’t they stone us?

23We must walk a three-day journey into the wilderness and sacrifice to Adonai our God—just as He tells us.”

24Pharaoh said, “I will let you go, so that you may sacrifice to Adonai your God in the wilderness. Only you must not go very far away. Pray for me.”
