Genesis 50:16-19

So they sent word to Joseph, saying, “Your father commanded us before he died, saying, ‘You are to say to Joseph, “I beg you, please forgive the transgression of your brothers and their sin, for they did you wrong.” ’ Now, please forgive the transgression of the servants of the God of your father.” And Joseph wept when they spoke to him.

[Vengeance is His, not mine.]
