Shemot 7:20-22

Orthodox Jewish Bible

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.

²² And the kharetumei Mitzrayim did so with their secret lore: and lev Pharaoh was hardened, neither did he pay heed unto them; as Hashem had said.
