Leviticus 19:9-18 (NRSV)
9 When you reap the harvest of your land, you shall not reap to the very edges of your field, or gather the gleanings of your harvest. 10 You shall not strip your vineyard bare, or gather the fallen grapes of your vineyard; you shall leave them for the poor and the alien: I am the Lord your God.
11 You shall not steal; you shall not deal falsely; and you shall not lie to one another. 12 And you shall not swear falsely by my name, profaning the name of your God: I am the Lord.
13 You shall not defraud your neighbor; you shall not steal; and you shall not keep for yourself the wages of a laborer until morning. 14 You shall not revile the deaf or put a stumbling block before the blind; you shall fear your God: I am the Lord.
15 You shall not render an unjust judgment; you shall not be partial to the poor or defer to the great: with justice you shall judge your neighbor. 16 You shall not go around as a slanderer[a] among your people, and you shall not profit by the blood[b] of your neighbor: I am the Lord.
33 When an alien resides with you in your land, you shall not oppress the alien. 34 The alien who resides with you shall be to you as the citizen among you; you shall love the alien as yourself, for you were aliens in the land of Egypt: I am the Lord your God.
Amos 5:21-24 (NRSV)
21 I hate, I despise your festivals,
and I take no delight in your solemn assemblies.
22 Even though you offer me your burnt offerings and grain offerings,
I will not accept them;
and the offerings of well-being of your fatted animals
I will not look upon.
23 Take away from me the noise of your songs;
I will not listen to the melody of your harps.
24 But let justice roll down like waters,
and righteousness like an ever-flowing stream.
