Psalms 119:21

Thou hast rebuked the proud -ComparePsalms 9:5. The meaning is, that God had done this not by word but by deed. The proud were everywhere rebuked by God, alike in his law, and in his providence. The connection seems to be this: the psalmist is meditating on the benefit or advantage of keeping the law of God; of a humble, pious life. His mind naturally adverts to what would be the opposite of this - or to this in contrast with an opposite course of life; and he says, therefore, that God had in every way, and at all times, manifested his displeasure against that class of people.
