'Justify' in the Bible

"Keep far from a false charge, and don't kill the innocent and righteous: for I will not justify the wicked.

If there be a controversy between men, and they come to judgment, and [the judges] judge them; then they shall justify the righteous, and condemn the wicked;

Far be it from me that I should justify you. Until I die I will not put away my integrity from me.

If you have anything to say, answer me. Speak, for I desire to justify you.

After the suffering of his soul, he will see the light and be satisfied. My righteous servant will justify many by the knowledge of himself; and he will bear their iniquities.
