16 And the Lord said to Moses: Say to Aaron, Stretch forth thy rod, and strike the dust of the earth: and may there be sciniphs in all the land of Egypt.
17 And they did so. And Aaron stretched forth his hand, holding the rod: and he struck the dust of the earth, and there came sciniphs on men and on beasts: all the dust of the earth was turned into sciniphs through all the land of Egypt.
18 And the magicians with their enchantments practiced in like manner, to bring forth sciniphs, and they could not and there were sciniphs as well on men as on beasts.
19 And the magicians said to Pharao This is the finger of God. And Pharao heart was hardened, and he hearkened not unto them, as the Lord had commanded.
20 The Lord also said to Moses: Arise early, and stand before Pharao: for he will go forth to the waters: and thou shalt say to him: Thus saith the Lord: Let my people go to sacrifice to me.
21 But if thou wilt not let them go, behold I will send in upon thee, and upon thy servants, and upon thy houses all kind of flies: and the houses of the Egyptians shall be filled with flies of divers kinds, and the whole land wherein they shall be.
22 And I will make the land of Gessen wherein my people is, wonderful in that lay, so that flies shall not be there: and thou shalt know that I am the Lord in the midst of the earth.
