Albert Barnes Commentary Psalms 119:56

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

This I had, because I kept your precepts—literally, “This was to me;” that is, this has happened to me; this has occurred.

This joyful remembrance of your law in the night of affliction (Psalms 119:50); this stability and firmness on my part in keeping your law when proud men have derided me (Psalms 119:51); this comfort which I have derived from meditating on your statutes (Psalms 119:52); this solicitude for the welfare of others (Psalms 119:53); this peace which I have enjoyed in your law in the house of my pilgrimage (Psalms 119:54); and this consolation which I have had in you in the night season (Psalms 119:55)—all this has been granted to me.

This was because I have kept your statutes; because I have sought to be obedient—to serve you—and to find my happiness in you.

These are the proper fruits and effects of keeping the law of God. Such peace does it impart; so much does it do to sustain and comfort the soul.
