John Gill Bible Commentary

My goodness,.... Not only good, but goodness itself; the donor of all the blessings of goodness to him; the author of all goodness in him; the provider of all goodness for him, laid up to be used hereafter. The Septuagint and Vulgate Latin versions render it my mercy, properly enough; that is, the God of "my mercy", as in Psa 59:10; who is all mercy, full of mercy, rich and plenteous in it; which is abundant, and from everlasting to everlasting. Or, "my grace" (d); the God of all grace, the giver of every grace, and who is able to make all grace to abound; and from whom every blessing of grace, and every particular grace, as faith, hope, and love, and all the supplies of grace, as well as every good and perfect gift, come: Christ is prevented with all the blessings of goodness; in him all fulness of grace dwells, and with him God keeps his mercy for evermore; and my fortress; garrison or strong hold: what fortresses or fortifications are to cities, whether natural or artificial, that is God to his people; all his perfections are on their side; and particularly they are kept by his power, as in a garrison, through faith unto salvation, Pe1 1:5; my high tower: the name of the Lord, which is himself, is a strong tower, where his righteous ones that flee to him are safe; and is an "high" one, where they are out of the reach of all their enemies, Pro 18:10; and my deliverer; that delivered him from his temporal enemies; and from his spiritual ones, from sin, Satan, and the world; from all afflictions and temptations, from wrath and ruin, death and hell; my shield; that protected him from all evil and danger; whose favour encompassed him as a shield; whose salvation was a shield to him; and more particularly the person, blood, righteousness, and sacrifice of his Son, called the shield of faith, Eph 6:16; and he in whom I trust; not in men, no, not in princes; but in the Lord only; in his Word, as the Targum; for things temporal and spiritual; for the blessings of grace here, and glory hereafter; of these several titles, see more on Psa 18:2; who subdueth my people under me; the people of Israel, all the tribes; whose hearts the Lord inclined to make him king over them all, Sa2 5:1. Or, "the people" (f); so the Targum, Syriac, and Arabic versions; the Heathen people, the Philistines, Ammonites, Edomites, Moabites, and Syrians; see Sa2 8:1. The former reading seems best, and is followed by the Septuagint, Vulgate Latin, and other versions: and this may be typical of the subduing of Christ's people under him; who are made willing, in the day of his power, to receive and own him as their King; profess subjection to his Gospel, and submit to his ordinances. (d) "gratia mea", Cocceius, Gejerus. (f) "pro" "populos", Piscator.
