'Says' in the Bible

What good is it, my brothers, if a man says he has faith, but has no works? Can faith save him?

and the Scripture was fulfilled which says, "Abraham believed God, and it was accounted to him as righteousness;" and he was called the friend of God.

Or do you think that the Scripture says in vain, "The Spirit who lives in us yearns jealously"?

But he gives more grace. Therefore it says, "God resists the proud, but gives grace to the humble."
