John Calvin Commentary Psalms 119:47

"And I will delight myself in thy commandments, Which I have loved." — Psalms 119:47 (ASV)

And I will delight myself. The sentiment in this verse is similar to what he had previously mentioned. The point is, he held God's commandments in such high esteem that he found nothing more pleasant to him than making them his constant theme of meditation.

By the term delight, he expresses the intensity of his love. The phrase I will lift up my hands, refers to the same thing. It is a sure indication that we eagerly desire a thing when we stretch out our hands to grasp and enjoy it. This simile, therefore, denotes the ardor of his desire.

If a man, by his demeanor and conduct, feigns such affection for God's law, and yet pays no regard to it in the affairs of life, he would justly be accused of the worst hypocrisy.

Again, he affirms that this affection, so earnest and ardent, springs from the sweetness of God's law, which has knit our hearts to it. Finally, he says, he would meditate on God’s testimonies. Along with the majority of commentators, I have no doubt that the word שוח shuach, denotes that silent and secret meditation in which God's children engage.
