'Speaks' in the Bible

Now we know that whatever the Law [of Moses] says, it speaks to those who are under the Law, so that [the excuses of] every mouth may be silenced [from protesting] and that all the world may be held accountable to God [and subject to His judgment].

(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.

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.
