'Justify' in the Bible

But he, desiring to justify himself, said unto Jesus, And who is my neighbor?

And he said unto them, Ye are they that justify yourselves in the sight of men; but God knoweth your hearts: for that which is exalted among men is an abomination in the sight of God.

if so be that God is one, and he shall justify the circumcision by faith, and the uncircumcision through faith.

And the scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand unto Abraham,'saying, In thee shall all the nations be blessed.
