1 Kings 2:4-6

New Century Version

⁴ And if you obey the Lord, he will keep the promise he made to me. He said: ‘If your descendants live as I tell them and have complete faith in me, a man from your family will always be king over the people of Israel.’

⁵ “Also, you remember what Joab son of Zeruiah did to me. He killed the two commanders of Israel’s armies: Abner son of Ner and Amasa son of Jether. He did this as if he and they were at war, although it was a time of peace. He put their blood on the belt around his waist and on his sandals on his feet. ⁶ Punish him in the way you think is wisest, but do not let him die peacefully of old age.
