Éxodo 7

and the heart of Pharaoh is strong, and he hath not hearkened unto them, as Jehovah hath spoken.

Y el corazón de Faraón se endureció, y no los escuchó; como Jehová lo había dicho.

And he hardened Pharaoh’s heart, that he hearkened not unto them; as the LORD had said.

Pharaoh’s heart was hardened, and he didn’t listen to them, as the LORD had spoken.
