1 Kings 2:28-34

Verse 28

Tidings came to Joab - He heard that Adonijah had been slain and Abiathar banished, and probably he had heard of David's dying charge to Solomon. Fearing therefore for his personal safety, he takes refuge at the tabernacle, as claiming Divine protection, and desiring to have his case decided by God alone; or perhaps a spark of remorse is now kindled; and, knowing that he must die, he wishes to die in the house of God, as it were under the shadow, that he might receive the mercy of the Almighty.
Verse 30

Nay; but I will die here - The altars were so sacred among all the people, that, in general, even the vilest wretch found safety, if he once reached the altar. This led to many abuses, and the perversion of public justice; and at last it became a maxim that the guilty should be punished, should they even have taken refuge at the altars. God decreed that the presumptuous murderer who had taken refuge at the altar should be dragged thence, and put to death; see Exo 21:14. The heathens had the same kind of ordinance; hence Euripides: - Εγω γαρ ὁστις μη δικαιος ων ανηρ Βωμον προσιζει, τον νομον χαιρειν εων, Προς την δικην αγοιμ' αν, αυ τρεσας θεους· Κακον γαρ ανδρα χρη κακως πασχειν αει.

Euripid. Frag. 42. Edit. Musg. "If an unrighteous man, availing himself of the law, should claim the protection of the altar, I would drag him to justice, nor fear the wrath of the gods; for it is necessary that every wicked man should suffer for his crimes."
Verse 34

So Benaiah - went up - and slew him - It appears he slew him at the very altar. Joab must have been both old and infirm at this time, and now he bleeds for Abner, he bleeds for Amasa, and he bleeds for Uriah. The two former he murdered; of the blood of the latter he was not innocent; yet he had done the state much service, and they knew it. But he was a murderer, and vengeance would not suffer such to live.
