'Unjust' in the Bible

Judge me, O God, and plead my cause against an ungodly nation: O deliver me from the deceitful and unjust man.

When a wicked man dieth, his expectation shall perish: and the hope of unjust men perisheth.

He that by usury and unjust gain increaseth his substance, he shall gather it for him that will pity the poor.

An unjust man is an abomination to the just: and he that is upright in the way is abomination to the wicked.

The just LORD is in the midst thereof; he will not do iniquity: every morning doth he bring his judgment to light, he faileth not; but the unjust knoweth no shame.
