Psalms 26:1

It is probable that David penned this psalm when he was persecuted by Saul and his party, who, to give some colour to their unjust rage, represented him as a very bad man, and falsely accused him of many high crimes and misdemeanors, dressed him up in the skins of wild beasts that they might bait him. Innocency itself is no fence to the name, though it is to the bosom, against the darts of calumny. Herein he was a type of Christ, who was made a reproach of men, and foretold to his followers that they also must have all manner of evil said against them falsely. Now see what David does in this case. I. He appeals to God's righteous sentence (Psa 26:1): "Judge me, O God! be thou Judge between me and my accusers, between the persecutor and the poor prisoner; bring me off with honour, and put those to shame that falsely accuse me." Saul, who was himself supreme judge in Israel, was his adversary, so that in a controversy with him he could appeal to no other then to God himself. As to his offences against God, he prays, Lord, enter not into judgment with me (Psa 143:2), remember not my transgressions (Psa 25:7), in which he appeals to God's mercy; but, as to his offences against Saul, he appeals to God's justice and begs of him to judge for him, as Psa 43:1.
