2 Samuel 8:15

And David reigned over all Israel; and David executed judgment and justice unto all his people.

Ver. 15. And David reigned over all Israel.] They were his loyal subjects at home; like as his foes abroad were his slaves and vassals; the bounds of his kingdom also were extended to the uttermost, as God had anciently promised.

And David executed judgment and justice.] Fuit severus in quos oportuit, et in quos oportuit misericors, saith Vatablus. Now it was, haply, that "the God of Israel said, the Rock of Israel spoke unto him, He that ruleth over men must be just, ruling in the fear of God." 2Sa 23:3 David was not puffed up with pride of his many victories, as Nebuchadnezzar; nor did he thereupon give himself to riot and intemperancy, as Alexander; nor did he tyrannise the more over his people, as Saul; but set himself to rule aright, that his throne might be established.
