Thematic Bible: Sometimes deferred for a considerable time

And you have with you Shimei son of Gera, the Benjamite of Bahurim, who cursed me with a grievous curse in the day when I went to Mahanaim. But he came down to meet me at the Jordan [on my return], and I swore to him by the Lord, saying, I will not put you to death with the sword. So do not hold him guiltless; for you are a wise man and know what you should do to him. His hoary head bring down to the grave with blood.

You know also what Joab son of Zeruiah did to me, and what he did to the two captains of the hosts of Israel, Abner son of Ner and Amasa son of Jether, whom he murdered, avenging in time of peace blood shed in war, and putting innocent blood of war on the girdle on his loins and on the sandals of his feet. Do therefore according to your wisdom, but let not his hoary head go down to Sheol (the place of the dead) in peace.
