Adam Clarke on Job 24:9

They pluck the fatherless from the breast - They forcibly take young children in order that they may bring them up in a state of slavery. This verse is the commencement of a new paragraph, and points out the arbitrary dealings of oppressors, under despotic governors.

Take a pledge of the poor - Oppressive landlords who let out their grounds at an exorbitant rent, which the poor laborers, though using the utmost diligence, are unable at all times to pay; and then the unfeeling wretch sells then up, as the phrase here is, or takes their cow, their horse, their cart, or their bed, in pledge, that the money shall be paid in such a time. This is one of the crying sins of some countries of Europe.
