Ye shall do no unrighteousness in judgement: thou shall not respect the person of the poor, nor honour the person of the mighty: but in righteousness shalt thou judge thy neighbour. (Lev 19:15)

If there be a controversy between men, and they come unto judgement, that the judges may judge them; then they shall justify the righteous, and condemn the wicked. (Deu 25:1)

God judgeth the righteous, and God is angry with the wicked every day. (Psa 7:11)

Judge not according to the appearance, but judge righteous judgement. (Joh 7:24)

Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters? Know ye not that we shall judge angels? how much more things that pertain to this life? If then ye have judgements of things pertaining to this life, set them to judge who are least esteemed in the church. I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his bretheren?(1Co 6:2-5)

But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgement. For by thy words thou shalt be justified, and by thy words thou shall be condemned. (Mat 12:36-37)
