Genesis 50:16-17

And they sent a messenger unto Joseph, saying, Thy father did command before he died, saying,

So shall ye say unto Joseph, Forgive, I pray thee now, the trespass of thy brethren, and their sin; for they did unto thee evil: and now, we pray thee, forgive the trespass of the servants of the God of thy father. And Joseph wept when they spake unto him.
