David here appeals to God, 1. As his witness that he had not done wrong; he could truly say, "I have done judgment and justice, that is, I have made conscience of rendering to all their due, and have not by force or fraud hindered any of their right." Take him as a king, he executed judgment and justice to all his people, Sa2 8:15. Take him in a private capacity, he could appeal to Saul himself that there was no evil or transgression in his hand, Sa1 24:11. Note, Honesty is the best policy and will be our rejoicing in the day of evil. 2. As his Judge, that he might not be wronged. Having done justice for others that were oppressed, he begs that God would do him justice and avenge him of his adversaries: "Be surety for thy servant, for good; undertake for me against those that would run me down and ruin me." He is sensible that he cannot make his part good himself, and therefore begs that God would appear for him. Christ is our surety with God; and, if he be so, Providence shall be our surety against all the world. Who or what shall harm us if God's power and goodness be engaged for our protection and rescue? He does not prescribe to God what he should do for him; only let it be for good, in such way and manner as Infinite Wisdom sees best; "only let me not be left to my oppressors." Though David had done judgment and justice, yet he had many enemies; but, having God for his friend, he hoped they should not have their will against him; and in that hope he prayed again, Let not the proud oppress me. David, one of the best of men, was oppressed by the proud, whom God beholds afar off; the condition therefore of the persecuted is better than that of the persecutors, and will appear so at last.

It is time for thee, Lord, to work,.... To send the Messiah, to work righteousness; to fulfil the law, and vindicate the honour of it, broken by men. It was always a notion of the Jews that the time of the Messiah's coming would be when it was a time of great wickedness in the earth; and which seems to agree with the word of God, and was true in fact; see Mal 2:17. Or to arise and have mercy on Zion, for which there is a fixed time: and its seems as if it would be when religion greatly declines, and profaneness abounds; when love is waxen cold, and there is no faith in the earth; and when the days are like those of Noah and Lot, Luk 17:26; or to take vengeance on wicked men, by sending down his judgments on them now, as well as he will punish them hereafter; for which a time is appointed, though no man knows of it. The words may be rendered, "it is time to work for the Lord" (o); so the Septuagint version; to which agrees the Targum,

"it is time to do the will of the Lord;''

and the Syriac and Arabic versions, "it is time to worship the Lord". It is proper, in declining times, for good men to bestir themselves and be in action, to attempt the revival of religion, to do all that in them lies to support the cause of God, and to vindicate his honour and glory;

for they have made void thy law; the whole word of God, the Scriptures; as atheists and deists, who deny the authority of them; Pharisees, who preferred their oral law to the written word, and by the traditions of the elders made it of none effect; Papists, by their unwritten traditions, and denying the common people the reading of the Scriptures in their mother tongue; and all false teachers, who wrest the Scriptures, and put false glosses on them, and handle the word of God deceitfully; and all profane sinners, who bid defiance to the law, and, as much as in them lies, abrogate it, and set up a law of their own, and frame mischief by it: or the law of faith may be meant; the Gospel of Christ, and the several truths of it, which are opposed, contradicted, and blasphemed by men of corrupt minds; and particularly the doctrine of justification by faith in Christ's righteousness; which are made void by the doctrine of works; and even the law itself is made void by the same: for not those that maintain the doctrine of Christ's righteousness, but those that establish their own, make void the law; presenting a righteousness to it, which is not answerable to its demands, Rom 3:31.
