Septuagint, Vulgate; Hebrew  go, not by a mighty hand

Exodus 7:4

4Pharaoh will not listen to you. Then I will lay my hand on Egypt and bring my hosts, my people the children of Israel, out of the land of Egypt by great acts of judgment.

Exodus 10:1

The Eighth Plague: Locusts

1Then the Lord said to Moses, “Go in to Pharaoh, for I have hardened his heart and the heart of his servants, that I may show these signs of mine among them,

Romans 9:16-18

16So then it depends not on human will or exertion,
Greek  not of him who wills or runs
but on God, who has mercy.
17For the Scripture says to Pharaoh, eFor this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth.” 18So then he has mercy on whomever he wills, and he hardens whomever he wills.
