And the LORD said unto Moses,
When you go
to return into Egypt, see that you do all those wonders before Pharaoh, whom I have put in your hand: but I will harden his heart, that he shall not let the people go.
All Commentaries on Exodus 4:21 Go To Exodus 4
Richard Challoner
AD 1781
I shall harden: Not by being the efficient cause of his sin; but by withdrawing from him, for his just punishment, the dew of grace that might have softened his heart; and so suffering him to grow harder and harder.
