2 Kings 14:6 - Joseph Benson’s Commentary on the Old and New Testaments

But the children of the murderers he slew not In this he acted like a good man, and showed both faith and courage, in that he would obey the command of God, though it might be attended with great hazard to himself, and was not moved to cut off the children, through fear lest they should raise a faction against him, and take revenge for their fathers' death. Very different is the custom pursued in many kingdoms, in which, if any one be guilty of high treason, not only he, but his children likewise, who neither partake nor are conscious of his traitorous practices, are equally devoted to destruction.
