(10) My defence.--Literally, as in margin, my shield is upon God. (Comp. Psalm 62:7, "In God is my salvation," where the Hebrew is as here, "God is my shield-bearer.") Another explanation appears in Milton's translation--

"On God is cast

My defence, and in Him lies,

In Him who both just and wise,

Saves the upright at heart at last."

Verse 10. - My defense is of God; literally, my shield is on God; i.e. "rests on him" (Kay) - is upheld by him. Which sayeth the upright in heart (comp. Psalm 125:4).

7:10-17 David is confident that he shall find God his powerful Saviour. The destruction of sinners may be prevented by their conversion; for it is threatened, If he turn not from his evil way, let him expect it will be his ruin. But amidst the threatenings of wrath, we have a gracious offer of mercy. God gives sinners warning of their danger, and space to repent, and prevent it. He is slow to punish, and long-suffering to us-ward, not willing that any should perish. The sinner is described, ver. 14-16, as taking more pains to ruin his soul than, if directed aright, would save it. This is true, in a sense, of all sinners. Let us look to the Saviour under all our trials. Blessed Lord, give us grace to look to thee in the path of tribulation, going before thy church and people, and marking the way by thine own spotless example. Under all the persecutions which in our lesser trials mark our way, let the looking to Jesus animate our minds and comfort our hearts.My defence is of God,.... Or "my shield is in" or "of God" (e); God was his shield, his protector and defender; see Psalm 3:3; or "my shield is with God"; that is, Christ, who was the shield his faith made use of against every spiritual enemy, was with God; he was with him as the Word and Son of God from all eternity, and as the living Redeemer of his people before his incarnation; and he is now with him as their intercessor and advocate, who pleads in defence of them, and opposes himself, his blood and righteousness, to all the charges and accusations of Satan;

which saveth the upright in heart: who have the truth of grace in them, wisdom in the hidden part; who are sincere in their affections, purposes, and designs, in their faith, hope, and love; and act from real principles of truth and love, in the integrity of their souls; for these light and gladness are sown, to them grace and glory are given, and no good thing is withheld from them; they are saved by God from sin, Satan, the world, death, and hell, and every enemy, with a spiritual and everlasting salvation.
