Exodus 9:7

Exo 9:7 And Pharaoh sent, and, behold, there was not one of the cattle of the Israelites dead. And the heart of Pharaoh was hardened, and he did not let the people go.

Ver. 7. And the heart of Pharaoh was hardened. ] Like a smith’s anvil, he grew harder for hammering. There was little need to say to Pharaoh, as the smith did to the Landgrave of Thuring, Durescite, durescite, O in felix Lantgravi. a He hardened fast enough.
