Charles H. Spurgeon on Psalms 119:12

In this verse we have two things, 1. An acknowledgment of God's blessedness, Blessed art thou, O LORD; i.e., being possessed of all fulness, thou hast an infinite complacency in the enjoyment of thyself; and thou art he alone in the enjoyment of whom I can be blessed and happy; and thou art willing and ready to give out of thy fulness, so that thou art the fountain of blessedness to thy creatures. 2. A request or petition, Teach me thy statutes; q.d., seeing thou hast all fulness in thyself, and art sufficient to thy own blessedness; surely thou hast enough for me. There is enough to content thyself, therefore enough to satisfy me. This encourages me in my address.

Again, Teach me that I may know wherein to seek my blessedness and happiness, even in thy blessed self; and that I may know how to come by the enjoyment of thee, so that I may be blessed in thee. Further, Thou art blessed originally, the Fountain of all blessing; thy blessedness is an everlasting fountain, a full fountain; always pouring out blessedness: O, let me have this blessing from thee, this drop from the fountain. William Wisheart, in "Theologia, or, Discourses of God, "1716.
