Charles H. Spurgeon on Psalms 12:5

"The oppression of the poor." Insolent and cruel oppressing of the poor is a sin that brings desolating and destroying judgments upon a people. God sent ten wasting judgments one after another upon Pharaoh, his people, and land, to revenge the cruel oppression of his poor people. "Rob not the poor, because he is poor: neither oppress the afflicted in the gate: for the Lord will plead their cause." Proverbs 22:22, 23. To rob and oppress the rich is a great sin; but to rob and oppress the poor is a greater; but to rob and oppress the poor because he is poor, and wants money to buy justice, is the top of all inhumanity and impiety. To oppress anyone is sin; but to oppress the oppressed is the height of sin. Poverty, and want, and misery, should be motives to pity; but oppressors make them the whetstone of their cruelty and severity, and therefore the Lord will plead the cause of his poor oppressed people against their oppressors without fee or fear; yea, he will plead their cause with pestilence, blood, and fire. Gog was a great oppressor of the poor (Ezekiel 38:8-14), and God pleads against him with pestilence, blood, and fire (verse 22); "and I will plead against him, with pestilence and with blood; and I will rain upon him, and upon his bands, and upon the many people that are with him, an overflowing rain, and great hailstones, fire, and brimstone.
