COMMENTARY ON PSALMS - VOLUME 2 effectual, not only because he will be faithful on his part, but also because he will keep his people from falling away through their own inconstancy.
34 My covenant will I not break. As the true knowledge of God's mercy can only be obtained from his word, he enjoins us to keep our eyes intently fixed upon his covenant. The more excellent and invaluable a blessing it is, "Never to be rejected after having been once adopted by him," the more difficult it is for us to believe its truth. And we know how many thoughts from time to time present themselves to our minds, tempting us to call it in question. That the faithful, therefore, may not harass themselves beyond measure in debating in their own minds whether or no they are in favor with God, they are enjoined to look to the covenant, and to embrace the salvation which is offered to them in it. God here commends to us his own faithfulness, that we may account his promise sufficient, and that we may not seek the certainty of our salvation any where else. He had said above, If the children of David break my statutes; and now, alluding to that breach, he declares that he will not requite them as they requite him, My covenant will I not break, implying, that although his people may not altogether act in a manner corresponding to their vocation, as they ought to do, he will not suffer his covenant to be broken and disannulled on account of their fault, because he will promptly and effectually prevent this in the way of blotting out their sins by a gratuitous pardon. He is still pursuing the illustration of the preceding proposition, I will not suffer my faithfulness to fail; promising not only to be faithful on his side, as we say, but also that what he has promised shall take full effect, in despite of all the impediments which men may cast in the way; for he will strive against their sins, that by means of them the fruit of his goodness may not be prevented from reaching them. When the Jews, by their ingratitude and treachery, revolted from him, the covenant was not disannulled, because it was founded upon the perfect immutability of his nature. And still, at the present day, when our sins mount even to the heavens, the goodness of God fails not to rise above them, since it is far above the heavens.
35. Once have I sworn by my holiness. God now confirms by an oath what he previously stated he had promised to David; from which it appears that it was not a matter of small importance; it being certain that God would not interpose his holy name in reference to what was of no consequence. It is a token of singular loving-kindness for him, upon seeing us prone to distrust, to provide a remedy for it so compassionately. We have, therefore, so much the less excuse if we do not embrace, with true and unwavering faith, his promise which is so strongly ratified, since in his deep interest about our salvation, he does not withhold his oath, that we may yield entire credence to his word. If we do not reckon his simple promise sufficient, he adds his oath, as it were, for a pledge. The adverb once, 1032 denotes that the oath is irrevocable, and that therefore we have not the least reason
