Albert Barnes Commentary Proverbs 28:3

"A needy man that oppresseth the poor Is [like] a sweeping rain which leaveth no food." — Proverbs 28:3 (ASV)

People raise a man of the people, poor like themselves, to power. They find him the worst oppressor of all, plundering them to their last morsels, like the storm-rain which sweeps off the seed grain instead of bringing fertility.
