Psalms 51:3

For I acknowledge my transgressions— אדע adang; I know, I am conscious of my transgression. When David saw himself in the parable, and had pronounced his own condemnation, he then saw his sins in their proper aggravations, and his iniquity was ever before him. His own conscience condemned him, and he was in perpetual fear of the effects of the divine displeasure. Dr. Chandler; who, differing in sentiment from Dr. Delaney, thinks that David was greatly insensible of his guilt, and enjoyed the fruits of his crimes without remorse many months after he had committed the sins that he now confesses. No man could call him to account, or had courage enough to put him in mind of his heinous offences; and even God had not yet interposed to awaken his conscience, and bring him to a becoming sense of the guilt that he had contracted; so that he hoped for impunity, and continued easy in the prospect of it, till awakened by Nathan.
