¹² But Jehovah hardened Pharaoh in his stubbornness, so that he refused to listen, just as the Lord had predicted to Moses.

¹³ Then the Lord said to Moses, “Get up early in the morning and stand before Pharaoh and tell him, ‘Jehovah the God of the Hebrews says, “Let my people go to worship me. ¹⁴ This time I am going to send a plague that will really speak to you and to your servants and to all the Egyptian people, and prove to you there is no other God in all the earth.
