Midrash sobre I Reyes 3:30

"And you shall provide yourselves with cities" (Numbers 35:11), this is what the verse says, "Good and upright is the Lord, therefore He shows sinners the way." (Psalms 25:8) "Remember Your mercy, O God, and your lovingkindness." (Psalms 25:6). David said, Master of the Universe, were it not for the fact that Your lovingkindness preceded the First Man, he would not have been able to stand, as it says "For the day you eat of it [the tree of knowledge of good and evil] you will surely die" (Genesis 2:17). And You did not do this; rather, You brought him out from the Garden of Eden and he lived for 930 years(!) and only after that did he die. Why did you do that to him, to drive him out from the Garden of Eden, as it says (Genesis 3:24) "and He drove out the man"? Why was he driven out, since he brought death upon the generations, and he was sentenced to immediate death? Rather, You had mercy upon him and drove him off, just as the accidental killer is exiled to a city of refuge. Thus it says, "Remember Your mercy, O God, and Your lovingkindness, etc." Once Moshe stood and the Holy Blessed One told him, "Provide yourselves with cities...", Moshe said "Master of the Universe, this one killed by accident in the south or the north; how will he know where the city of refuge is, that he may flee to it?" God replied, "'Set for yourselves the path... [i.e. to the cities of refuge]' (Deuteronomy 19:3), orient for yourselves the path so that you will not be mistaken and find the blood avenger and he will kill you "and there will be for him no death penalty" (Deuteronomy 19:6)." He [Moshe] said again, "How?" He [God] said to him, set up for yourselves signs [istlayot] pointing to the cities of refuge, that they will know where to travel. And on every sign write "Killer to the city of refuge", as it says "prepare for yourselves the way". Thus said David, "Good and upright is the Lord, therefore He shows sinners the way." If for killers He makes a path and a road for them to flee by and be saved, all the more so for righteous! "He guides the humble in justice, and teaches the humble His way" (Psalms 25:9). "And the killer shall flee there who has killed a soul by accident" -- but not on purpose. If he kills on purpose and he says "I accidentally killed" and flees to the cities of refuge, the Holy Blessed One says, even if he flees and enters to My altar, you shall kill him, as it says (Exodus 21:14) "And if a person schemes, etc [against another, and kills him treacherously, you shall take him from My very altar to be put to death]". And who was it who fled to the altar and was killed? Yoav, as it says (I Kings 2:28) "When the news reached Joab, he fled to the Tent of the LORD [and grasped the horns of the altar]...". And it says (II Samuel 23:8) "Tahchemonite, the chief officer" -- he did not know that it is written in the Torah "And if a person schemes, etc" that he went and grasped the horns of the altar. Rather it says "Those killed by the court are not buried in the graves of their fathers, rather they alone; it is better for me that I die here and be buried in the graves of my fathers". (I Kings 3:30-31) "Benaiah reported back to the king that Joab had answered thus and thus, and the king said, 'Do just as he said; strike him down and bury him, and remove guilt from me and my father’s house for the blood of the innocent that Joab has shed.'" And why was he killed? For so David his [Shlomo's] father had commanded him -- "Further, you know what Joab son of Zeruiah did to me, what he did to the two commanders of Israel’s forces, Abner son of Ner and Amasa son of Jether: he killed them" (I Kings 2:5). What did he do to him...
