Romans 9:15 in the King James Version
For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.
Context
14 What shall we say then? Is there unrighteousness with God? May it never be!
15 For he said to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.”
16 So then it is not of him who wills, nor of him who runs, but of God who has mercy.
