Romans 9:18 in the King James Version
Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.
Context
17 For the Scripture says to Pharaoh, “For this very purpose I caused you to be raised up, that I might show in you my power, and that my name might be proclaimed in all the earth.”
18 So then, he has mercy on whom he desires, and he hardens whom he desires.
19 You will say then to me, “Why does he still find fault? For who withstands his will?”
