Exodus 8:20-22

New Catholic Bible

²⁰ This is what the Lord did. A huge swarm of flies flew into the house of Pharaoh, the houses of his ministers, and all over the land of Egypt. The area was devastated because of the flies.

²¹ Pharaoh summoned Moses and Aaron and said, “Go and sacrifice to your God in the land.”

²² But Moses answered, “It would not work, for the sacrifice that we are going to make to the Lord, our God, is an abomination to the Egyptians. Could we perform a sacrifice that is an abomination to the Egyptians in their sight? Would they not stone us?^[a]
