Psalms 12:5

“The writer intimates his confidence by depicting God's actions (compare Psa 9:19; Psa 10:12) as coming to save the poor at whom the wicked sneer (Psa 10:5).”

“For the oppression of the poor - That is, on account of the wrong done to the poor in the manner specified above - by the abuse of the power of speech. On account of the slanders uttered against them, or the frauds perpetrated on them by the abuse of this power. The reference is to the wrongs done when no confidence could be placed in men’s words; when they uttered words of “vanity” and “flattery” Psalms 12:2; when promises were made only to be broken, and obligations assumed never to be fulfilled. In such a state of things the “poor” were the most likely to suffer. In performing service for others - in daily labor on a farm or in a mechanical employment - they would depend for support, on…”
