'Says' in the Bible

and one of you says to them, "Go in peace, keep warm and eat well," but you do not give them what the body needs, what good is it?

And the scripture was fulfilled that says, "Now Abraham believed God and it was counted to him for righteousness," and he was called God's friend.

For we all stumble in many ways. If someone does not stumble in what he says, he is a perfect individual, able to control the entire body as well.

Or do you think the scripture means nothing when it says, "The spirit that God caused to live within us has an envious yearning"?

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