C. F. Keil and Franz Delitzsch on Psalms 25:6

Psa 25:6

The supplicatory reminiscere means, may God never forget to exercise His pity and grace towards him, which are (as the plurals imply) so rich and superabundant. The ground on which the prayer is based is introduced with כּי (nam, or even quoniam). God’s compassion and grace are as old in their operation and efficacy as man’s feebleness and sin; in their counsels they are eternal, and therefore have also in themselves the pledge of eternal duration (Psa 100:5; Psa 103:17).
