Thou hast rebuked the proud that are cursed, which do err from thy commandments.
Psalm 119:21 belongs to a psalm that exalts the sacredness of God's law. Its commandments are the rule of life, defining the difference between right and wrong and between truth and error. In that setting the verse teaches that God rebukes the proud, who are cursed because they err and stray from His commandments. That rebuke applies when the wickedness of the world has reached the point at which the Lord will intervene.
