25 And it was so from that day forward,  that he made it a statute and an ordinance for Israel unto this day.
25 David made this a statute and ordinance for Israel from that day to this.
25 And he made it a statute and a rule for Israel from that day forward to this day.
25 From that day on, David made that the rule in Israel - and it still is.
25 So it was, from that day forward; he made it a statute and an ordinance for Israel to this day.
25 From then on David made this a decree and regulation for Israel, and it is still followed today.
Matthew Henry's Commentary on 1 Samuel 30:25
Commentary on 1 Samuel 30:21-31
(Read 1 Samuel 30:21-31)
What God gives us, he designs we should do good with. In distributing the spoil, David was just and kind. Those are men of Belial indeed, who delight in putting hardships upon their brethren, and care not who is starved, so that they may be fed to the full. David was generous and kind to all his friends. Those who consider the Lord as the Giver of their abundance, will dispose of it with fairness and liberality.
