Directions for Praising God. A song or psalm of David. 1 O God, my heart is fixed; I will sing and give praise, even with my glory. 2 Awake, psaltery and harp: I myself will awake early. 3 I will praise thee, O Lord, among the people: and I will sing praises unto thee among the nations.

We may here learn how to pray as well as praise. 1. We must be public-spirited in prayer, and bear upon our hearts, at the throne of grace, the concerns of the church of God, Ps. 108:6.
