John Calvin Commentary Psalms 35:10

"All my bones shall say, Jehovah, who is like unto thee, Who deliverest the poor from him that is too strong for him, Yea, the poor and the needy from him that robbeth him?" — Psalms 35:10 (ASV)

O Jehovah! who is like thee? Here he explains more fully the nature of his joy in the salvation of God of which he had spoken, showing that it consisted in his ascribing entirely to God the deliverance he had obtained. Men, in general, praise God in such a manner that he scarcely obtains the tenth part of his due.

But David, distinguishing him from all others, distinctly declares that the whole glory of his deliverance is due to him alone. And certainly, we yield to God what belongs to him only when, ascribing to him his own power, we rest all our hopes on him. For what purpose does it serve to loudly celebrate the name of God with our mouths, if we tear his power and goodness to pieces at our pleasure?

David, therefore, in the true spirit of godliness, extols the greatness of God with this high encomium: that he is the guardian and defender of the poor, and rescues the needy and afflicted from the hand of those who oppress them. It is as if he had said, "It is God’s special duty to help the miserable."

By these words we are taught to cling to the hope of better things in adversity; for the power and resources of our enemies, however great they may be, are no reason for us to lose our confidence, since God declares to us from heaven that he reigns expressly for the purpose of resisting the strong and powerful.

If the children of this world, who employ their power in injuring and oppressing the weak, had the least degree of sound understanding, it would certainly serve to restrain their audacity and prevent them from proceeding further in provoking the wrath of God.
