'Judge' in the Bible

Do not speak against one another, brothers and sisters. He who speaks against a fellow believer or judges a fellow believer speaks against the law and judges the law. But if you judge the law, you are not a doer of the law but its judge.

But there is only one who is lawgiver and judge -- the one who is able to save and destroy. On the other hand, who are you to judge your neighbor?

Do not grumble against one another, brothers and sisters, so that you may not be judged. See, the judge stands before the gates!
