<or Psalm of David.>> O God, my heart is {a} fixed; I will sing and give praise, even with my glory.

(a) This earnest affection declares that he is free from hypocrisy and that sluggishness does not stop him.

Wesley's Notes

108:1 Glory - With my tongue.

Jamieson-Fausset-Brown Bible Commentary

PSALM 108

Ps 108:1-13. This Psalm is composed of Ps 108:1-5 of Ps 57:7-11; and Ps 108:6-12 of Ps 60:5-12. The varieties are verbal and trivial, except that in Ps 108:9, "over Philistia will I triumph," differs from Ps 60:8, the interpretation of which it confirms. Its altogether triumphant tone may intimate that it was prepared by David, omitting the plaintive portions of the other Psalms, as commemorative of God's favor in the victories of His people.

Matthew Henry's Concise Commentary

108:1-13 We may usefully select passages from different psalms, as here, Ps 57; 60, to help our devotions, and enliven our gratitude. When the heart is firm in faith and love, the tongue, being employed in grateful praises, is our glory. Every gift of the Lord honours and profits the possessor, as it is employed in God's service and to his glory. Believers may pray with assured faith and hope, for all the blessings of salvation; which are secured to them by the faithful promise and covenant of God. Then let them expect from him help in every trouble, and victory in every conflict. Whatever we do, whatever we gain, God must have all the glory. Lord, visit all our souls with this salvation, with this favour which thou bearest to thy chosen people.
