Bible Verses About Punishments: Sometimes deferred for a considerable time

"Moreover, you are aware of what Yo'av the son of Tz'ruyah did to me, that is, what he did to the two commanders of the armies of Isra'el, Avner the son of Ner and 'Amasa the son of Yeter - he killed them, shedding the blood of war in peacetime, putting the blood of war on the belt around his waist and the shoes on his feet.

Therefore, act according to your wisdom; don't let his gray head go down to the grave in peace.

"Finally, you have with you Shim'i the son of Gera the Binyamini, from Bachurim. He laid a terrible curse on me when I was on my way to Machanayim; but he came down to meet me at the Yarden; so I swore to him by ADONAI that I would not have him put to death with the sword.

Now, however, you should not let him go unpunished. You are a wise man, and you will know what you should do to him - you will bring his gray head down to the grave with blood."
