Psalms 107:42

Iniquity - Sin; wickedness; evil.

The righteous shall see it - The wicked are as inconsiderate as they are obstinate and headstrong.

And rejoice - To have such ample proofs that God ruleth in the earth, and that none that trust in him shall be desolate.

All iniquity shall stop her mouth - God's judgments and mercies are so evident, and so distinctly marked, that atheism, infidelity, and irreligion are confounded, and the cause of error and falsehood has become hopeless. It was only the mouth that could do any thing; and that only by lies, calumnies, and blasphemies: but God closes this mouth, pours contempt upon the head and judgment upon the heart. This may also be applied to the case of the Israelttes and the Babylonians. The former, when they turned to God, became righteous; the latter were a personification of all iniquity.

The righteous shall see it, and rejoice - Shall see all these changes; shall see in their own case the proofs of the divine favor. They shall thus have occasion for praise.

And all iniquity shall stop her mouth - The wicked shall be silenced; they shall be dumb. The righteous shall find, in these varied scenes, occasion for praise and joy; the wicked shall be able to find no occasion for complaining or murmuring. The divine dealings shall be manifestly so just, and so worthy of universal approval, that, even though the wicked are disposed to complain against God, they will be able to find nothing which will justify them in such complaints.
