Job 24:10
They go about naked, without clothing; hungry, they carry the sheaves;
Deuteronomy 24:19
"When you reap your harvest in your field and forget a sheaf in the field, you shall not go back to get it. It shall be for the sojourner, the fatherless, and the widow, that the LORD your God may bless you in all the work of your hands.
Amos 2:7-8
those who trample the head of the poor into the dust of the earth and turn aside the way of the afflicted; a man and his father go in to the same girl, so that my holy name is profaned;
Amos 5:11-12
Therefore because you trample on the poor and you exact taxes of grain from him, you have built houses of hewn stone, but you shall not dwell in them; you have planted pleasant vineyards, but you shall not drink their wine.
