Ps 138:1-8. David thanks God for His benefits, and anticipating a wider extension of God's glory by His means, assures himself of His continued presence and faithfulness.
1. I will praise thee with my whole heart -- (Compare Ps 9:1).
before the gods -- whether angels (Ps 8:5); or princes (Ex 21:6; Ps 82:6); or idols (Ps 97:7); denotes a readiness to worship the true God alone, and a contempt of all other objects of worship.
2. (Compare Ps 5:7).
thy word above all thy name -- that is, God's promise (2Sa 7:12-16), sustained by His mercy and truth, exceeded all other manifestations of Himself as subject of praise.
3-5. That promise, as an answer to his prayers in distress, revived and strengthened his faith; and, as the basis of other revelations of the Messiah, it will be the occasion of praise by all who hear and receive it (Ps 68:29, 31; Isa 4:3).
5. for great is the glory -- or, |when the glory shall be great,| in God's fulfilling His purposes of redemption.
6, 7. On this general principle of God's government (Isa 2:11; 57:15; 66:2), he relies for God's favor in saving him, and overthrowing his enemies.
knoweth afar off -- their ways and deserts (Ps 1:6).
8. God will fulfil His promise.
