1 Kings 2:25 Meaning and Commentary

1 Kings 2:25

And King Solomon sent by the hand of Benaiah the son of
Jehoiada
Orders to execute him, and proper persons to do it; perhaps some of the Cherethites and Pelethites under him, to assist at least in it:

and he fell upon him, that he died;
Benaiah rushed in upon him with his men, and thrust his sword into him, and killed him; executions used to be done in those times and countries by great personages, as the instances of Gideon, Doeg, and others, show, and not by common executioners.

1 Kings 2:25 In-Context

23 Then King Solomon made a vow before the LORD : “May God strike me and even kill me if Adonijah has not sealed his fate with this request.
24 The LORD has confirmed me and placed me on the throne of my father, David; he has established my dynasty as he promised. So as surely as the LORD lives, Adonijah will die this very day!”
25 So King Solomon ordered Benaiah son of Jehoiada to execute him, and Adonijah was put to death.
26 Then the king said to Abiathar the priest, “Go back to your home in Anathoth. You deserve to die, but I will not kill you now, because you carried the Ark of the Sovereign LORD for David my father and you shared all his hardships.”
27 So Solomon deposed Abiathar from his position as priest of the LORD, thereby fulfilling the prophecy the LORD had given at Shiloh concerning the descendants of Eli.
