Shemot 7:16-18

Orthodox Jewish Bible

¹⁶ And thou shalt say unto him, Hashem Elohei HaIvrim hath sent me unto thee, saying, Let My people go, that they may serve Me in the midbar: and, hinei, hitherto thou wouldest not hear.

¹⁷ Thus saith Hashem, In this thou shalt know that I am Hashem: hinei, I will strike with the matteh that is in Mine yad upon the mayim which are in the Nile, and they shall be turned to dahm.

¹⁸ And the dag (fish) that is in the Nile shall die, and the Nile shall stink; and the Egyptians shall loathe to drink of the mayim of the Nile.
