'Says' in the Bible

What use is it, my brethren, if someone says he has faith but he has no works? Can that faith save him?

and one of you says to them, “Go in peace, be warmed and be filled,” and yet you do not give them what is necessary for their body, what use is that?

and the Scripture was fulfilled which says, “And Abraham believed God, and it was reckoned to him as righteousness,” and he was called the friend of God.

For we all stumble in many ways. If anyone does not stumble in what he says, he is a perfect man, able to bridle the whole body as well.

But He gives a greater grace. Therefore it says, “God is opposed to the proud, but gives grace to the humble.”
