Genesis 50:19 - Matthew Poole's English Annotations on the Holy Bible

It is God's prerogative to take vengeance, which I dare not usurp. See Deuteronomy 32:35. Or, can I do what I please with you without God's leave? Therefore fear him rather than me, and upon your experience of his wonderful care and kindness to you, believe that God will not, and therefore that I neither can nor will do you any hurt. But it is not unusual to put the Hebrew he for halo, as it is Genesis 27:36 1 Samuel 2:28 2 Samuel 23:19 1 Kings 16:31, &c.; and so the words may be very well rendered, Am not I under God, i.e. subject to his will, a minister of his providence? Dare I destroy those whom God so eminently designed to save? Dare I punish those whom God hath pardoned.
