Verse 1
Psalm 30:1-12. Literally, “A Psalm-Song” - a composition to be sung with musical instruments, or without them - or, “Song of the dedication,” etc. specifying the particular character of the Psalm. Some suppose that of David should be connected with the name of the composition, and not with “house”; and refer for the occasion to the selection of a site for the temple (1 Chronicles 21:26-30; 1 Chronicles 22:1). But “house” is never used absolutely for the temple, and “dedication” does not well apply to such an occasion. Though the phrase in the Hebrew, “dedication of the house of David,” is an unusual form, yet it is equally unusual to disconnect the name of the author and the composition. As a “dedication of David‘s house” (as provided, Deuteronomy 20:5), the scope of the Psalm well corresponds with the state of repose and meditation on his past trials suited to such an occasion (2 Samuel 5:11; 2 Samuel 7:2). For beginning with a celebration of God‘s delivering favor, in which he invites others to join, he relates his prayer in distress, and God‘s gracious and prompt answer.
lifted me up — as one is drawn from a well (Psalm 40:2).
Verse 2
healed me — Affliction is often described as disease (Psalm 6:2; Psalm 41:4; Psalm 107:20), and so relief by healing.
Verse 3
The terms describe extreme danger.
soul — or, “myself.”
grave — literally, “hell,” as in Psalm 16:10.
hast kept me … pit — quickened or revived me from the state of dying (compare Psalm 28:1).
Verse 4
remembrance — the thing remembered or memorial.
holiness — as the sum of God‘s perfections (compare Psalm 22:3), used as name (Exodus 3:15; Psalm 135:13).
Verse 5
Relatively, the longest experience of divine anger by the pious is momentary. These precious words have consoled millions.
Verse 6-7
What particular prosperity is meant we do not know; perhaps his accession to the throne. In his self-complacent elation he was checked by God‘s hiding His face (compare Psalm 22:24; Psalm 27:9).
Verse 7
troubled — confounded with fear (Psalm 2:5).
Verses 8-11
As in Psalm 6:5; Psalm 88:10; Isaiah 38:18, the appeal for mercy is based on the destruction of his agency in praising God here, which death would produce. The terms expressing relief are poetical, and not to be pressed, though “dancing” is the translation of a word which means a lute, whose cheerful notes are contrasted with mourning, or (Amos 5:16) wailing.
Verse 11
sackcloth — was used, even by kings, in distress (1 Chronicles 21:16; Isaiah 37:1) but “gladness,” used for a garment, shows the language to be figurative.
Verse 12
Though “my” is supplied before “glory” it is better as in Psalm 16:9, to receive it as used for tongue, the organ of praise. The ultimate end of God‘s mercies to us is our praise to Him.
