Éxodo 9

and the heart of Pharaoh is strong, and he hath not sent the sons of Israel away, as Jehovah hath spoken by the hand of Moses.

Y el corazón de Faraón se endureció, y no dejó ir á los hijos de Israel; como Jehová lo había dicho por medio de Moisés.

And the heart of Pharaoh was hardened, neither would he let the children of Israel go; as the LORD had spoken by Moses.

The heart of Pharaoh was hardened, and he didn’t let the children of Israel go, just as the LORD had spoken through Moses.
