Gen 50:17 (KJV) — 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.
Gen 50:17 (NIV) — 'This is what you are to say to Joseph: I ask you to forgive your brothers the sins and the wrongs they committed in treating you so badly.' Now please forgive the sins of the servants of the God of your father." When their message came to him, Joseph wept.
