Voice of God
In the Abrahamic religions, the voice of God is a communication from God to human beings through sound with no known physical source.
In Rabbinic Judaism, such a voice is known as a bat kol (Hebrew: בַּת קוֹל baṯ qōl, literally "daughter of voice"), a "heavenly or divine voice which proclaims God's will or judgment". It differed from prophecy in that God had a close relationship with the prophet, while the bat kol could be heard by any individual or group regardless of their level of connection to God.
