"And Joshua wrote these words in the book of
the law of God; and he took a large stone and set it up there under
the oak that was by the sanctuary of the LORD. Joshua said to all
the people, 'Behold, this stone shall be for a witness against us,
for it has heard all the words of the LORD which He spoke to us;
thus it shall be for a witness against you, so that you do not deny
your God.'" (Joshua 24:26,27).
