Charles Ellicott Commentary Proverbs 28:3

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

A poor man that oppresseth the poor.— If the recollection of his own former troubles has not softened his heart towards his poor neighbors, he will be rendered more callous to their sufferings.

Is like a sweeping rain which leaveth no food.— That sweeps away grain and soil, instead of bringing plenty with it.
