Psalms 144:2 - Matthew Poole's English Annotations on the Holy Bible

My goodness; or, my mercy; or, the God of my mercy, as God is called, Psalms 59:10,17; the name of God being easily understood from the foregoing verse. Or, he who is exceeding good or merciful to me, as good as goodness itself; the abstract being put for the concrete, as it is frequently in speeches of God, who is called wisdom, truth, goodness, &c.; and, sometimes of men, as Psalms 12:1 Proverbs 10:29, where faithfulness and uprightness are put for faithful and upright men. Who subdueth my people under me; who has disposed my people's hearts to receive and obey me as their king.
