Charles H. Spurgeon on Psalms 119:14

I have rejoiced in the way of thy testimonies. Delight in the word of God is a sure proof that it has taken effect upon the heart, and so is cleansing the life. The Psalmist not only says that he does rejoice, but that he has rejoiced. For years it had been his joy and bliss to give his soul to the teaching of the word. His rejoicing had not only arisen out of the word of God, but out of the practical characteristics of it. The Way was as dear to him as the Truth and the Life. There was no picking and choosing with David, or if indeed he did make a selection, he chose the most practical first.

As much as in all riches. He compared his intense satisfaction with God's will with that of a man who possesses large and varied estates, and the heart to enjoy them. David knew the riches that come of sovereignty and which grow out of conquest; he valued the wealth which proceeds from labour, or is gotten by inheritance: he knew "all riches." The gracious king had been glad to see the gold and silver poured into his treasury that he might devote vast masses of it to the building of the Temple of Jehovah upon Mount Zion. He rejoiced in all sorts of riches consecrated and laid up for the noblest uses, and yet the way of God's word had given him more pleasure than even these. Observe that his joy was personal, distinct, remembered, and abundant. Wonder not that in the previous verse he glories in having spoken much of that which he had so much enjoyed: a man may well talk of that which is his delight.
