Psalms 89:17

“For thou art the glory of their strength, etc.] By which they walk, and do all they do, exercise every grace, and discharge their duty; they have their strength from Christ, as well as their righteousness, without whom they can do nothing, but all things through him strengthening them; and as his righteousness exalts them, his strength adorns and glorifies them; how glorious and beautiful does a believer look, that is strong in the Lord, and in the power of his might, in the grace that is in Christ, and in the exercise of faith on him, giving glory to God; on whom the power of Christ rests, and it overshadows, and in whose weakness his strength is made perfect! and in thy favour our horn…”

“For thou art the glory of their strength - The ornament; the beauty; the honor; that is, Their strength derives its beauty and honor, not from anything in themselves, but from the fact that it is derived from thee. The strength thus imparted is an honor or ornament in itself; it is an honor and glory to them that it is imparted to them. And in thy favor - Or, by thy favor, or good pleasure. Our horn shall be exalted - The horn is a symbol of power. Compare Psalms 22:21, note; Psalms 75:4; Daniel 7:8, note; Job 16:15, note. The meaning here is, that their power had been derived from God; or that all which contributed to their exaltation and honor in the world, had been derived from him.…”

“The glory - To thee alone belongs the glory of all their valiant achievements. Psalms 89:19”

“89:17-18 The Lord protects his people with the same power by which he established the created order.”
