• "For there is no partiality with God." —Romans 2:11, New World Translation of the Holy Scripture (De10:17, 2Ch19:7, Ac10:34,35)
• "But he that doeth wrong shall receive for the wrong which he hath done: and there is no respect of persons." —Colossians 3:25, KJV
• "My dear brothers and sisters, how can you claim that you have faith in our glorious Lord Jesus Christ if you favor some people more than others? For instance, suppose someone comes into your meeting dressed in fancy clothes and expensive jewelry, and another comes in who is poor and dressed in shabby clothes. If you give special attention and a good seat to the rich person, but you say to the poor one, 'You can stand over there, or else sit on the floor'—well, doesn't this discrimination show that you are guided by wrong motives? Listen to me, dear brothers and sisters. Hasn't God chosen the poor in this world to be rich in faith? Aren't they the ones who will inherit the Kingdom he promised to those who love him? And yet, you insult the poor man! Isn't it the rich who oppress you and drag you into court? Aren't they the ones who slander Jesus Christ, whose noble name you bear? Yes indeed, it is good when you truly obey our Lord's royal command found in the scriptures: 'Love your neighbor as yourself'. But if you pay special attention to the rich, you are committing a sin, for you are guilty of breaking that law." —Epistle of James 2:1-9, NLT
• "But the wisdom that comes from heaven is first of all pure; then peace-loving, considerate, submissive, full of mercy and good fruit, impartial and sincere." -Epistle of James 3:17, NIV

Islam

• "O you who have believed, be persistently standing firm in justice, witnesses for Allah, even if it be against yourselves or parents and relatives. Whether one is rich or poor, Allah is more worthy of both. So follow not [personal] inclination, lest you not be just. And if you distort [your testimony] or refuse [to give it], then indeed Allah is ever, with what you do, Acquainted." Quran 4:135.
• "O you who have believed, be persistently standing firm for Allah, witnesses in justice, and do not let the hatred of a people prevent you from being just. Be just; that is nearer to righteousness. And fear Allah ; indeed, Allah is Acquainted with what you do." Quran 5:8.
