Job 20:19ESV·author unknown

For he has crushed and abandoned the poor; he has seized a house that he did not build.

Matthew Henry Presbyterian @wholebiblehenry

The instances here given of the miserable condition of the wicked man in this world are expressed with great fulness and fluency of language, and the same thing returned to again and repeated in other words. Let us therefore reduce the particulars to their proper heads, and observe, I. What his wickedness is for which he is punished. 1.

John Gill Reformed Baptist @doctorgill

Because he hath oppressed and hath forsaken the poor,.... Having oppressed, crushed, and broken the poor to pieces, he leaves them so without pity and compassion for them, and without giving them any relief; he first by oppression makes them poor, or however poorer still, and then leaves them in such circumstances; for this does not suppose that he once was a favourer of them...

oppressed--whereas he ought to have espoused their cause (Ch2 16:10). forsaken--left helpless. house--thus leaving the poor without shelter (Isa 5:8; Mic 2:2).
