Charles H. Spurgeon on Psalms 59:3

For, lo, they lie in wait for my soul. They were in ambuscade for the good man's life. He knew their design and cried to God to be rescued from it. Like wild beasts they crouched, and waited to make the fatal spring; but their victim used effectual means to baffle them, for he laid the matter before the Lord. While the enemy lies waiting in the posture of a beast, we wait before God in the posture of prayer, for God waits to be gracious to us and terrible towards our foes. The mighty are gathered against me. None of them were absent from the muster when a saint was to be murdered. They were too fond of such sport to be away. The men at arms who ought to have been fighting their country's battles, are instead thereof hunting a quiet citizen; the gigantic monarch is spending all his strength to slay a faithful follower. Not for my transgression, not for my sin, O Lord. He appeals to Jehovah that he had done no ill. His only fault was, that he was too valiant and too gracious, and was, besides, the chosen of the Lord, therefore the envious king could not rest till he had washed his hands in the blood of his too popular rival. We shall always find it to be a great thing to be innocent; if it does not carry our cause before an earthly tribunal, it will ever prove the best of arguments in the court of conscience, and a standing consolation when we are under persecution. Note the repetition of his declaration of integrity. David is sure of his innocence. He dares repeat the plea.
