17 Or else, if you do not let My people go, I will send the swarm of flies on you and on your servants, on your people and into your houses. The houses of the Egyptians will be full of the swarm of flies including the ground that they stand on.
18 “But on that day I will set apart the land of Goshen, where My people are dwelling—except no swarm of flies will be there—so that you may know that I, Adonai, am in the midst of the earth.
19 I will make a distinction between My people and your people. By tomorrow this sign will happen.”
20 Adonai 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.
21 So Pharaoh called for Moses and for Aaron and said, “Go! Sacrifice to your God—in the land.”
22 But 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?
23 We must walk a three-day journey into the wilderness and sacrifice to Adonai our God—just as He tells us.”
