Job 20:19
Because he hath oppressed and hath forsaken the poor; because he hath violently taken away an house which he builded not; Because he hath oppressed and hath forsaken the poor; because he hath violently taken away an house which he builded not;
The saying occurs inside the extended debate between Job and his three friends over his afflictions, running from chapter 4 through chapter 31. More precisely it belongs to their arguments in chapters 3 to 31 concerning the cause and purpose of human suffering. It stands in the closing part of that exchange, where the friends condemned him for what looked like self-righteousness while he dismissed their words as unjust condemnation.
As spoken there it is an accusation leveled at Job and is not trustworthy as a description of how he actually lived. Like all the friends uttered, it was really said, yet it came out of their own wisdom and observation and was wrongly forced onto his situation. Understood generally it declares that wrongdoing is finally punished and rightdoing finally rewarded, so that whoever crushes and abandons the poor and seizes by violence a house he never built will come under judgment. Affliction, adversity and suffering by themselves are no proof that the sufferer lies under divine displeasure.
