'Says' in the Bible

What [is] the benefit, my brothers, if someone says [that he] has faith but does not have works? That faith [is] not able to save him, [is it]?

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

For we all stumble [in] many [ways]. If anyone does not stumble in what he says, he [is] a perfect individual, able to hold in check his whole body also.

Or do you think that in vain the scripture says, "The spirit which he caused to dwell in us desires jealously"?

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