“He takes no delight in the strength of the horse, nor any pleasure in the legs of a man. Jehovah takes pleasure in those who fear Him, those who hope in His mercy” (Psalm 147:10-11).
Since I’ve been lacking in the fecundity department for a while, I thought I’d just quote (not endorse as a true Christian) John Calvin on these verses:
“After the Psalmist has shown that there is proof of the divine goodness in every part of the world, he takes particular notice that men have no strength but what is given them from above, and this he adds with the express purpose of checking the pride by which almost all men are inflamed, and which leads them to trust in their own strength. The meaning of the passage is, that let man come in the preparation of his own strength, and with all the assistance’s that seem to him most prevalent, this will only issue in smoke and vanity; nay, that in arrogating the very least to himself, this will only be a hindrance in the way of the mercy of God, by which alone we stand.The strength of the horse is mentioned by synecdoche to denote any kind of protection. Not that God is displeased with those things in themselves considered which he has given us as helps, but it is necessary that we be withdrawn from a false confidence in them, for very commonly when any resource is at hand, we are foolishly intoxicated and lifted up with pride. He opposes the fear of God therefore to the strength both of men and of horses, and places his hope in his mercy, intimating that it is highly incumbent upon us to show our moderation in worshipping God with reverence and holiness, and depending upon his grace. Hence we learn that he only condemns that strength which would take from God the honor due to him” (John Calvin).
