Shemot 7:13-15

Orthodox Jewish Bible

¹³ And He hardened lev Pharaoh, that he paid heed not unto them; as Hashem had said.

¹⁴ And Hashem said unto Moshe, the lev Pharaoh is hardened, he refuseth to let the people go.

¹⁵ Get thee unto Pharaoh in the boker; hinei, he goeth out unto the mayim; and thou shalt stand by the bank of the Nile to meet him; and the matteh which was turned to a nachash shalt thou take in thine yad.
