Adam Clarke on 1 Kings 2:30

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."
