20 (8:16) And Hashem said unto Moshe, Rise up early in the boker, and stand before Pharaoh; hinei, he cometh forth to the mayim; and say unto him, Thus saith Hashem, Let My people go, that they may serve Me.
21 (8:17) Else, if thou wilt not let My people go, hineni, I will send swarms of arov upon thee, and upon thy avadim, and upon thy people, and into thy batim (houses); and the batim (houses) of the Egyptians shall be full of swarms of arov, and also the ground whereon they are.
22 (8:18) And I will deal differently in that day with Eretz Goshen, in which My people dwell, that no swarms of arov shall be there; to the end thou mayest know that I am Hashem in the midst of the earth.
23 (8:19) And I will put a distinction between My people and thy people; tomorrow shall this Ot be.
24 (8:20) And Hashem did so; there came a grievous swarm of arov into the bais Pharaoh, into batim of his avadim, into kol Eretz Mitzrayim; the land was corrupted from the swarm of arov.
25 (8:21) And Pharaoh called for Moshe, for Aharon, and said, Go ye, sacrifice to Eloheichem in the land.
26 (8:22) And Moshe said, It is not meet so to do; for we shall sacrifice the to'avot Egyptians to Hashem Eloheinu; lo, shall we sacrifice the to'avot Egyptians before their eyes, and will they not stone us?
