Romans 9:17-19 New Revised Standard Version, Anglicised (NRSVA)
17 For the scripture says to Pharaoh, ‘I have raised you up for the very purpose of showing my power in you, so that my name may be proclaimed in all the earth.’ 18 So then he has mercy on whomsoever he chooses, and he hardens the heart of whomsoever he chooses.
God’s Wrath and Mercy
19 You will say to me then, ‘Why then does he still find fault? For who can resist his will?’
