Wonders - A word used only of portents performed to prove a divine interposition; they were the credentials of God's messengers.

I will harden Pharaoh's heart - I will permit his stubbornness and obstinacy still to remain, that I may have the greater opportunity to multiply my wonders in the land, that the Egyptians may know that I only am Jehovah, the self-existent God. See Clarke's note on Exodus 4:21.

And I will harden Pharaoh's heart,.... See Gill on Exodus 4:21.

and multiply my signs and my wonders in the land of Egypt; work one miracle and wonderful sign after another, until they are all wrought intended to be wrought; and which he had given Moses power to do, and until the end should be answered and obtained, the letting go of the children of Israel.

And I will harden Pharaoh's heart, and multiply my signs and my wonders in the land of Egypt.

3. I will harden Pharaoh's heart-This would be the result. But the divine message would be the occasion, not the cause of the king's impenitent obduracy.

7:1-7 God glorifies himself. He makes people know that he is Jehovah. Israel is made to know it by the performance of his promises to them, and the Egyptians by the pouring out of his wrath upon them. Moses, as the ambassador of Jehovah, speaking in his name, laid commands upon Pharaoh, denounced threatenings against him, and called for judgments upon him. Pharaoh, proud and great as he was, could not resist. Moses stood not in awe of Pharaoh, but made him tremble. This seems to be meant in the words, Thou shalt be a god unto Pharaoh. At length Moses is delivered from his fears. He makes no more objections, but, being strengthened in faith, goes about his work with courage, and proceeds in it with perseverance.
