Exodus 9:35 Meaning and Commentary

Exodus 9:35

And the heart of Pharaoh was hardened
Instead of being softened, as it seemed to be when under the plague, it became harder and harder when delivered from it:

neither would he let the children of Israel go;
though he had so absolutely promised it, and assured them that he would not keep them, and that they should not stay any longer:

as the Lord had spoken by Moses;
that so his heart would be hardened until the signs and wonders were multiplied upon him, God designed to perform, ( Exodus 4:21 ) ( 7:3 ) .

Exodus 9:35 In-Context

33 And Moses went forth from Pharao out of the city, and stretched out his hands to the Lord, and the thunders ceased and the hail, and the rain did not drop on the earth.
34 And when Pharao saw that the rain and the hail and the thunders ceased, he continued to sin; and hardened his heart, and the heart of his servants.
35 And the heart of Pharao was hardened, and he did not send forth the children of Israel, as the Lord said to Moses.
