This may be read as the praise of the risen Jesus celebrating Him who has now redeemed Him from death. He calls on the saints, as it were, to help Him in this praise, and He rehearses something of His experience, and of His cry, when under the fear of death (Heb. 5:7), and then resumes His praise, showing that the resurrection had unsealed His lips or awakened His glory. (See also Psa. 116.)
But the resurrection of the Lord is in one character of it a pledge of the coming deliverance of His Israel, and thus of the resurrection of the nation. This is to be remembered when reading this Psalm.
NOTE—Connection may be discovered between Psalm 28; 29, and 30. Psalm 28—The godly cry to be delivered from death, or the power of the pit. Psalm 29—The Lord answers, as with an earthquake, delivering the prisoner. (Matt. 28:2, Rev. 6; 11; 16; see also Psa. 18:7.) Psalm 30—The delivered one owns this with praise—that as God had now broken His silence with such a voice of power, so would His ransomed break theirs with a voice of praise. (Compare Psa. 28:1, with 30:12.)
