'Justify' in the Bible

Keep thee far from a false matter; and the innocent and righteous slay thou not: for I will not justify the wicked.

If there be a controversy between men, and they come unto judgment, that the judges may judge them; then they shall justify the righteous, and condemn the wicked.

If I justify myself, mine own mouth shall condemn me: if I say, I am perfect, it shall also prove me perverse.

God forbid that I should justify you: till I die I will not remove mine integrity from me.

If thou hast any thing to say, answer me: speak, for I desire to justify thee.

Which justify the wicked for reward, and take away the righteousness of the righteous from him!

He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.
