John Gill Bible Commentary

Do not I hate them, O Lord, that hate thee?.... Wicked men are haters of God; of his word, both law and Gospel; of his ordinances, ways, and worship; of his people, cause, and interest; and therefore good men hate them: not as men, as the creatures of God, and as their fellow creatures, whom they are taught by the Gospel to love, to do good unto, and pray for; but as haters of God, and because they are so; not their persons, but their works; and for the truth of this the omniscient God is appealed unto; and am not I grieved with those that rise up against thee? as wicked men do, in their hearts, in their words, and in their actions. They rebel against God, and contend with him, which is folly and madness; and this is grieving to good men, because of their insolence and impudence, the ruin and destruction they expose themselves to, and the dishonour done to God: and this arises from their great love and strong affection for him, not being able to bear such behaviour to him; as a man is filled with grief and indignation when another rises up against his father or his friend; see Psa 119:136.
