Matthew Poole and continuators on 1 Kings 2:31

31 And the king said unto him, Do as he hath said , and fall upon him, and bury him; that thou mayst take away the innocent blood which Joab shed, from me, and from the house of my father.

Either 1. Kill him in that place: and for so doing, Solomon might seem to have Warrant from God, Exod. 21. 14. and might further design by this just severity, to deter future Offenders, by shewing, that no place nor person should protect them from the stroak of Justice. Or rather, 2. let him Die as he is resolved; kill him, though he be there; take him by violence from that place, and then kill him: for Exod. 21. 14. doth not command the Ruler to kill the Murderer there, but to remove him thence, to take him from the Altar, that he may die. And seeng this might be done, why should Solomon unnecessarily stain the Altar with his Blood?

i. e. Both the Guilt of it, which would rest upon my Fathers and my Family, if it went unpunished; and the scandal and reproach of it, that neither this, nor following Ages may imagine that it was done by David's secret instigation, or with his consent.
