Exodus 7:14-16

Darby Translation

¹⁴ And Jehovah said to Moses, Pharaoh's heart is hardened: he refuseth to let the people go.

¹⁵ Go unto Pharaoh in the morning—behold, he will go out unto the water—and take thy stand by the bank of the river in front of him; and take in thy hand the staff that was turned into a serpent.

¹⁶ And say unto him, Jehovah the God of the Hebrews has sent me to thee, saying, Let my people go, that they may serve me in the wilderness; but behold, hitherto thou hast not hearkened.
