1 Kings 2:46 Meaning and Commentary

1 Kings 2:46

So the king commanded Benaiah the son of Jehoiada, which went
out
From the presence of the king, and took Shimei with him to the proper place of execution, it not being fitting to execute him before the king:

and fell upon him, that he died;
put him to death by the sword:

and the kingdom was established in the hand of Solomon;
Adonijah the usurper, and Joab the general of the army, who took on his side, being both put to death; and Abiathar the high priest deposed, who was in the same conspiracy; and Shimei, a dangerous and troublesome man, dispatched, there remained none to give any disturbance; so that he now sat easy and quiet on his throne, and things with respect to the civil government were on a firm and settled foundation.

1 Kings 2:46 In-Context

44 And the king said to Shimei, Thou knowest all the evil, of which thine heart is guilty to thee, which evil thou didest to [David] my father; the Lord hath yielded thy malice into thine head. (And the king said to Shimei, Thou knowest all the evil which thy heart is guilty of, which evil thou didest to my father David; and now the Lord shall yield thy malice onto thy own head.)

45 And king Solomon shall be blessed; and the throne of David shall be stable before the Lord till into without end.
