Charles H. Spurgeon on Psalms 73:22

Among the many arguments to prove the penman of the Scripture inspired by the Spirit of God, this is not the last and least —that the penmen of holy writ do record their own faults and the faults of their dearest and nearest relatives. For instance hereof, how coarsely doth David speak of himself: So foolish was I, and ignorant: I was as a beast before thee. And do you think that the face of St. Paul did look the more foul by being drawn with his own pencil, when he says, "I was a murderer, a persecutor, the greatest of sinners, "etc? This is not usual in the writings of human authors, who praise themselves to the utmost of what they could, and rather than lose a drop of applause they will lick it up with their own tongues. Tully writes very copiously in setting forth the good service which he did the Roman state, but not a word of his covetousness, of his affecting popular applause, of his pride and vain glory, of his mean extraction and the like. Whereas, clean contrary, Moses sets down the sin and punishment of his own sister, the idolatry and superstition of Aaron his brother, and his own fault in his preposterous striking the rock, for which he was excluded the land of Canaan. Thomas Fuller.
