Shemot 7:19-21

Orthodox Jewish Bible

¹⁹ And Hashem spoke unto Moshe, Say unto Aharon, Take thy matteh, and stretch out thine yad upon the mayim of Mitzrayim, upon their streams, upon their rivers, and upon their ponds, and upon all their mikveh of mayim, that they may become dahm; and that there may be dahm throughout kol Eretz Mitzrayim, both in vessels of wood, and in vessels of stone.

²⁰ And Moshe and Aharon did so, as Hashem commanded; and he lifted up the matteh, and smote the waters that were in the Nile, in the sight of Pharaoh, and in the sight of his avadim; and all the mayim that were in the Nile were turned to dahm.

²¹ And the dag (fish) that was in the Nile died; and the Nile stank, and the Egyptians could not drink of the mayim of the Nile; and there was dahm throughout kol Eretz Mitzrayim.
