Exodus 7:16-18

Amplified Bible, Classic Edition

¹⁶ And say to him, The Lord, the God of the Hebrews has sent me to you, saying, Let My people go, that they may serve Me in the wilderness; and behold, heretofore you have not listened.

¹⁷ Thus says the Lord, In this you shall know, recognize, and understand that I am the Lord: behold, I will smite with the rod in my hand the waters in the [Nile] River, and they shall be turned to blood.

¹⁸ The fish in the river shall die, the river shall become foul smelling, and the Egyptians shall loathe to drink from it.
