Albert Barnes Commentary Psalms 119:12

"Blessed art thou, O Jehovah: Teach me thy statutes." — Psalms 119:12 (ASV)

Blessed art thou, O Lord—Blessed are you as the author of such a law. This language of benediction or doxology is an outbreak of feeling or adoration in view of such a law—so good, so holy, so suited to direct and guide man. The mind is full of the subject; and the lips give vent to the feeling of gratitude and joy that such a law had been revealed to people.

Teach me thy statutes—Make me more and more acquainted with a law so pure, so rich, so valuable.
