Melachim Alef 2:31

31 And HaMelech said unto him, Do as he hath said, and fall upon him, and bury him; that thou mayest take away from me the demei chinnam (innocent blood), the shefach dahm of Yoav, even from against the Bais Avi.

Melachim Alef 2:31 Meaning and Commentary

1 Kings 2:31

And the king said unto him, do as he hath said, and fall upon
him, and bury him
Let him die where he is, slay him upon the spot, and then bury him; not by the altar, but in his own sepulchre, as later related, that in, give orders to bury him there; for Benaiah being a priest, could not be concerned in the burial of him, and besides it was below the dignity of his office:

((See Gill on 1 Chronicles 27:2) where Gill advances resaons for Benaiah not being a priest. Editor.)

that thou mayest take away the innocent blood, which Joab shed, from
me, and from the house of my father;
which had been too long connived at, and had called for vengeance; and now here was a proper opportunity upon fresh sins committed to avenge it, and so remove the guilt, which lay upon him and his father's house, for not inflicting deserved punishment on him for it.

Melachim Alef 2:31 In-Context

29 And it was told Melech Sh’lomo that Yoav was fled unto the Ohel Hashem; and, hinei, he is beside the Mizbe’ach. Then Sh’lomo sent Benayah Ben Yehoyada, saying, Go, fall upon him.

30 And Benayah came to the Ohel Hashem, and said unto him, Thus saith HaMelech, Come forth. And he said, Nay; but I will die here. And Benayah brought HaMelech word again, saying, Thus said Yoav, and thus he answered me.

31 And HaMelech said unto him, Do as he hath said, and fall upon him, and bury him; that thou mayest take away from me the demei chinnam (innocent blood), the shefach dahm of Yoav, even from against the Bais Avi.

32 And Hashem shall return his dahm upon his own rosh, who fell upon two anashim more tzadikim and tovim than he, and killed them with the cherev, Dovid Avi not knowing thereof: Avner Ben Ner, Sar Tzava Yisroel, and Amasa Ben Yeter, Sar Tzava Yehudah.

33 Let their dahm therefore turn back upon the rosh Yoav, and upon the rosh of his zera l’olam; but upon Dovid, and upon his Zera, and upon his Bais, and upon his Kisse, let there be shalom ad olam from Hashem.
