Jamieson, Fausset y Brown sobre Salmos 33

PSALM 33 Psa 33:1-22. 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. 1-3. The sentiment falls in with Psa 32:11 (compare 1Co 14:15). The instruments (Psa 92:3; 144:9) do not exclude the voice.

4-9. Reasons for praise: first, God's truth, faithfulness, and mercy, generally; then, His creative power which all must honor.

10-11. In God's providence He thwarts men's purposes and executes His own. heathen--literally, "nations."

12-19. 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.

20-22. waiteth--in earnest expectation.
