Charles Ellicott Commentary Psalms 119:56

"This I have had, Because I have kept thy precepts. HHETH." — Psalms 119:56 (ASV)

This I had, because ... —Literally, This was to me, etc., i.e., this consoling recollection of the mercies of God, of His covenant grace, was to him, happened, or came to him, in consequence of his habitual obedience. Virtue is indeed then most truly its own reward, in times of quiet reflection, like the night, when to the guilty come remorse and apprehension, but to the good man “calm thoughts regular as infant’s breath.”
