'Speaks' in the Bible

Now we know that whatever the law says speaks to those who are subject to the law, so that every mouth may be shut and the whole world may become subject to God’s judgment.

Likewise, David also speaks of the blessing of the man God credits righteousness to apart from works:

(as it is written [in Scripture], “I have made you a father of many nations”) in the sight of Him in whom he believed, that is, God who gives life to the dead and calls into being that which does not exist.

But the righteousness that comes from faith speaks like this: Do not say in your heart, “Who will go up to heaven?” that is, to bring Christ down

For with the heart a person believes [in Christ as Savior] resulting in his justification [that is, being made righteous—being freed of the guilt of sin and made acceptable to God]; and with the mouth he acknowledges and confesses [his faith openly], resulting in and confirming [his] salvation.
