Matthew Henry and continuators on Psalms 119:12

12 Blessed art thou, O Lord : teach me thy statutes.

Here, 1. David gives glory to God: "Blessed art thou, O Lord! Thou art infinitely happy in the enjoyment of thyself and hast no need of me or my services; yet thou art pleased to reckon thyself honoured by them; assist me therefore, and then accept me." In all our prayers we should intermix praises. 2. He asks grace from God: "Teach me thy statutes; give me to know and do my duty in every thing. Thou art the fountain of all blessedness; O let me have this drop from that fountain, this blessing from that blessedness: Teach me thy statutes, that I may know how to bless thee, who art a blessed God, and that I may be blessed in thee."
