Psalms 116:5

5 Jehovah is gracious. He comes now to point out the fruits of that love of which he spoke, setting before him God’s titles, in order that they might serve to preserve his faith in him. First, he denominates him gracious, because he is so ready graciously to render assistance. From this source springs that justice which he displays for the protection of his own people. To this is subjoined mercy, without which we would not deserve God’s aid. And as the afflictions which overtake us frequently appear to preclude the exercise of his justice, hence it follows that there is nothing better than to repose upon him alone; so that his fatherly kindness may engross our thoughts, and that no voluptuous pleasure may steal them away to any thing else. He then accommodates the experience of God’s benignity and equity to the preserving of the simple, that is, of such as, being undesigning, do not possess the requisite prudence for managing their own affairs. The term, rendered simple, is often understood in a bad sense, denoting persons inconsiderate and foolish, who will not follow wholesome advice. But, in this place, it is applied to those who are exposed to the abuse of the wicked, who are not sufficiently subtle and circumspect to elude the snares which are laid for them, — in short, to those who are easily overreached; while, on the contrary, the children of this world are full of ingenuity, and have every means at their command for maintaining and protecting themselves. David, therefore, acknowledges himself to be as a child, unable to consult his own safety, and totally unfit to ward off the dangers to which he was exposed. Hence the LXX. have not improperly translated the Hebrew term by the Greek, τὰ νήπια, little children. The amount is, that when those who are liable to suffering have neither the prudence nor the means of effecting their deliverance, God manifests his wisdom towards them, and interposes the secret protection of his providence between them and all the dangers by which their safety may be assailed. In fine, David holds forth himself as a personal example of this fact, in that, after being reduced to the greatest straits, he had, by the grace of God, been restored to his former state.
