Jamieson, Fausset & Brown's Commentary
Commentary on Psalms 33
Verse 3
a new song--fresh, adapted to the occasion (Psa 40:3; Psa 96:1).
play skilfully--(Compare Sa1 16:17).
Verses 4–5
Reasons for praise: first, God's truth, faithfulness, and mercy, generally; then, His creative power which all must honor.
Verses 6–8
In "word" and "breath"--or, "spirit," there may be an allusion to the Son (Joh 1:1) and Holy Spirit.
Verse 9
he spake--literally, "said."
it was--The addition of "done" weakens the sense (compare Gen 1:3-10).
Verses 10–11
In God's providence He thwarts men's purposes and executes His own.
heathen--literally, "nations."
Verse 12
The inference from the foregoing in Psa 33:12 is illustrated by God's special providence, underlying which is His minute knowledge of all men.
Verses 13–14
looketh--intently (Isa 14:16).
Verse 15
fashioneth--or, "forms," and hence knows and controls (Pro 21:1).
alike--without exception.
considereth--or, "understands"; God knows men's motives.
Verse 16
Men's usual reliances in their greatest exigencies are, in themselves, useless.
Verse 17
On the war horse (compare Job 39:19-25).
a vain thing--a lie, which deceives us.
Verses 18–19
Contrasted is God's guidance and power to save from the greatest earthly evil and its most painful precursor, and hence from all.
Verse 20
waiteth--in earnest expectation.
Verse 21
his holy name--(Compare Psa 5:12; Psa 22:22; Psa 30:4). Our faith measures mercy (Mat 9:29); and if of grace, it is no more of debt (Rom 11:6).
Next: Psalms Chapter 34
A call to lively and joyous praise to God for His glorious attributes and works, as displayed in creation, and His general and special providence, in view of which, the Psalmist, for all the pious, professes trust and joy and invokes God's mercy. (Psa. 33:1-22)
The sentiment falls in with Psa 32:11 (compare Co1 14:15). The instruments (Psa 92:3; Psa 144:9) do not exclude the voice.
