Proverbs 28:3 - Joseph Benson’s Commentary on the Old and New Testaments

A poor man that oppresseth the poor Who, being advanced into a place of authority, abuses it, to oppress those that are poor, and unable to resist him; is like a sweeping rain, or flood, which leaveth no food Which washeth away the very seeds that are in the earth, and spoils the corn and fruit which are upon it. He is the worst of all oppressors, because his low and base mind is made worse by his sudden elevation into a high condition, and his own necessities inflame his desires, and make him greedy to take all, yea, even the smallest advantages for enriching himself. This the ancients expressed by the similitudes of an empty horseleech, which sticks much more strongly than that which is already filled; and of a dry sponge, which licks up far more water than one which is wet before. See Lord Bacon's Adv. of Learning, lib. 8. cap. 2.
