John Gill Commentary Proverbs 14:31

"He that oppresseth the poor reproacheth his Maker; But he that hath mercy on the needy honoreth him." — Proverbs 14:31 (ASV)

He that oppresses the poor reproaches his Maker That does him any injury, either by scoffing at him, and reproaching him for his poverty; or by vexatious law suits; or by withholding from him his wages; or not giving him that relief which he ought: such an one not only injures the poor man; but reproaches God that made him, not only a man, but a poor man; and who is the Maker of the rich man also, (Proverbs 22:2);

but he that honors him has mercy on the poor ; he that is desirous of honoring God, and glorifying him, will give of his substance to the poor; having compassion on him in his necessitous circumstances, will relieve him; and in so doing he honors God, whose image the poor man bears, and who has commanded him so to do. The words may be rendered, "he that has mercy on the poor honors him"; that is, his Maker: so the Targum, "he that has mercy on him that suffers injury honors him."
