Romans 9:16-18

16So then [it is] not of him that wills, nor of him that runs, but of 1God that shews mercy.

17For the scripture says to Pharaoh, For this very thing I have raised thee up from amongst [men], that I might thus shew in thee my power, and so that my name should be declared in all the earth.

18So then, to whom he will he shews mercy, and whom he will he hardens.
