Proverbs 14:31

God is here pleased to interest himself more than one would imagine in the treatment given to the poor. 1. He reckons himself affronted in the injuries that are done them. Whosoever he be that wrongs a poor man, taking advantage against him because he is poor and cannot help himself, let him know that he puts an affront upon his Maker. God made him, and gave him his being, the same that is the author of our being; we have all one Father, one Maker; see how Job considered this, Job 31:15. God made him poor, and appointed him his lot, so that, if we deal hardly with any because they are poor, we reflect upon God as dealing hardly with them in laying them low, that they might be trampled upon. 2. He reckons himself honoured in the kindnesses that are done them; he takes them as done to himself, and will show himself accordingly pleased with them. I was hungry, and you gave me meat. Those therefore that have any true honour for God will show it by compassion to the poor, whom he has undertaken in a special manner to protect and patronise.

reproacheth his Maker--who is the God of such, as well as of the rich (Pro 22:2; Job 31:15; and specially Sa1 2:8; Psa 113:7).
