Thomas Aquinas, on Ps 18:11

“More to be desired than gold and many precious stones: and sweeter than honey and the honeycomb.”

“And he proves this in two ways. First, by experience. Second, from the effect. By experience, when he says, "For your servant keeps them"; as if to say: I can say they are sweet because I have tasted them, for I love them and experience them. No one can bear witness except he who experiences: Jn. 7: "If anyone is willing to do his will, he shall know of the doctrine whether it is from God or whether I speak of myself": Job 23: "My foot has followed his steps." From the effect, that is, from recompense, he proves the same when he says, "In keeping them there is great reward": Mt. 5: "Rejoice and be glad, for your reward is great in heaven." And he does not say "for keeping," but "in keeping them," because the very keeping of them is a great reward, namely the glory of the heart and its purity: 2 Cor. 1: "Our glory is this: the testimony of our conscience." And thus the law is commended for its honesty when he says, "in keeping them," and so on, because the honest is the same as virtue, and is desirable in itself.”
