4 And Hashem shall separate between the mikneh Yisroel and the mikneh Mitzrayim; and there shall nothing die of all that belongs to the Bnei Yisroel.
5 And Hashem appointed a mo'ed, saying, Tomorrow Hashem shall do this thing in the land.
6 And Hashem did that thing on the next day, and all the mikneh of Mitzrayim died; but of the mikneh of the Bnei Yisroel died not one.
7 And Pharaoh sent, and, hinei, there was not one of the mikneh Yisroel dead. And the lev Pharaoh was hardened, and he did not let HaAm go.
8 And Hashem said unto Moshe and unto Aharon, Take to you handfuls of piach of the furnace, and let Moshe sprinkle it toward Shomayim in the sight of Pharaoh.
9 And it shall become fine dust in kol Eretz Mitzrayim, and shall be a sh'khin (boil) breaking forth with festers upon adam, and upon behemah, throughout kol Eretz Mitzrayim.
10 And they took piach of the furnace, and stood before Pharaoh; and Moshe sprinkled it up toward Shomayim; and it became a sh'khin breaking forth with festers upon adam, and upon behemah.
