Exodus 7:13 - Clarke's commentary and critical notes on the Bible

And he hardened Pharaoh's heart, that he hearkened not unto them; as the LORD had said. And he hardened Pharaoh's heart - ויחזק לב פרעה vaiyechezak leb Paroh, "And the heart of Pharaoh was hardened," the identical words which in Exodus 7:22 are thus translated, and which should have been rendered in the same way here, lest the hardening, which was evidently the effect of his own obstinate shutting of his eyes against the truth, should be attributed to God. See Clarke's note on Exodus 4:21.
