Thematic Bible: Sometimes deferred for a considerable time

"Behold, there is with you Shimei the son of Gera the Benjamite, of Bahurim; now it was he who cursed me with a violent curse on the day I went to Mahanaim But when he came down to me at the Jordan, I swore to him by the LORD, saying, 'I will not put you to death with the sword.' "Now therefore, do not let him go unpunished, for you are a wise man; and you will know what you ought to do to him, and you will bring his gray hair down to Sheol with blood."

"Now you also know what Joab the son of Zeruiah did to me, what he did to the two commanders of the armies of Israel, to Abner the son of Ner, and to Amasa the son of Jether, whom he killed; he also shed the blood of war in peace. And he put the blood of war on his belt about his waist, and on his sandals on his feet. "So act according to your wisdom, and do not let his gray hair go down to Sheol in peace.
