Remember not the sins of my youth
Original sin, in which he was born, and the breakings forth of corrupt nature in infancy, he brought into the world with him, together with all the youthful lusts and vanities to which that age is addicted; and sometimes the sins of youth are in some persons remembered by God, and punished in old age; and if not, they are brought to remembrance through the dispensations of Providence: and the people of God are chastised for them then, and are ready to fear it is in a way of wrath; see ( Job 13:26 ) ; which the psalmist here deprecates; for this is not said in order to extenuate his sins, they being but youthful follies, imprudencies, and inadvertencies, sins committed through ignorance, when he had not the knowledge of things he now had; nor as if he had lived so holy a life, that there were no sins of his to be taken notice of but what he had committed in his younger days; but rather this is to be considered as a confession of his having sinned from his youth upwards unto that time, as in ( Jeremiah 3:25 ) ; and therefore entreat, that God would not remember his sins, so as to correct him for them in wrath and hot displeasure; neither the sins he had formerly been guilty of, nor those of a later date; which he next mentions;
nor my transgressions;
his more notorious and glaring ones; such as murder and adultery, in the case of Uriah and Bathsheba, and which now stared him in the face; and on account of these, and as a chastening for them, this unnatural rebellion of his son's, which was now raised against him, was suffered to befall him, as had been foretold to him, ( 2 Samuel 12:11 ) ;
according to thy mercy remember thou me, for thy goodness' sake, O
Lord;
he pleads no merit nor goodness of his own, but casts himself upon the mercy, grace, and goodness of God; in which he was certainly right; and on that account prayed and hoped for deliverance from his present troubles, and for discoveries of the pardon of his sins unto him, which is what he means by remembering him.
