Psalms 9:12 - Clarke's commentary and critical notes on the Bible

When he maketh inquisition for blood, he remembereth them: he forgetteth not the cry of the humble. When he maketh inquisition for blood - This not only applies to the Canaanites, Moabites, Ammonites, and Philistines, who shed the blood of God's people unjustly, but to all the nations of the earth who, to enlarge their territory, increase their wealth, or extend their commerce, have made destructive wars. For the blood which such nations have shed, their blood shall be shed. If man should make no inquisition for this iniquitously spilt blood, God will do it, for he remembers them; and the cry of the humbled, distressed people, driven to distraction and ruin by such wars, is not forgotten before him.
