2 Samuel 19:19-23 - David's Mercy To Shimei
19 He said: I beg you not to punish me! Please forget what I did when you left Jerusalem. Do not even think about it. 20 I know I was wrong and have sinned. That is why I wanted to be the first one from the northern tribes to meet you.
21 But Abishai shouted: You should be killed for cursing Jehovah's chosen king!
22 David exclaimed: Abishai, what will I do with you and your brother Joab? Is it your job to tell me who has done wrong? I have been made king of all Israel today. No one will be put to death! 23 David promised Shimei that he would not be killed.
