John Trapp on Proverbs 28:3

Verſ. 3. A poor man that oppreſſeth the poor, &c. Such an oppreſſour bites hard (as a lean louſe doth) makes clean work, plunders to the life, as they ſay omnia corradit & converret. Poor men ſhould pitty poor men, as knowing the miſery of poverty: but to oppreſs or defraud their comperes, is greateſt inhumanity, as that mercileſs fellow ſervant did, Matth. 18.28. &c. A Weeſel is a ravenous beaſt as well as a Lyon, a Sparrow-hauk as greedy as an Eagle, and more mercy is to be expected from thoſe more noble creatures, than from the baſe and abject.
