1 Kings 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.

1 Kings 2:31 In-Context

29 And it is declared to king Solomon that Joab hath fled unto the tent of Jehovah, and lo, near the altar; and Solomon sendeth Benaiah son of Jehoiada, saying, `Go, fall upon him.'
30 And Benaiah cometh in unto the tent of Jehovah, and saith unto him, `Thus said the king, Come out;' and he saith, `Nay, but here I die.' And Benaiah bringeth back the king word, saying, `Thus spake Joab, yea, thus he answered me.'
31 And the king saith to him, `Do as he hath spoken, and fall upon him, and thou hast buried him, and turned aside the causeless blood which Joab shed, from off me, and from off the house of my father;
32 and Jehovah hath turned back his blood on his own head, who hath fallen on two men more righteous and better than he, and slayeth them with the sword, -- and my father David knew not -- Abner son of Ner, head of the host of Israel, and Amasa son of Jether, head of the host of Judah;
33 yea, turned back hath their blood on the head of Joab, and on the head of his seed to the age; and for David, and for his seed, and for his house, and for his throne, there is peace unto the age, from Jehovah.'
