Joshua 24:23-27

Now therefore put away, said he, the strange gods which are among you, and incline your heart unto the LORD God of Israel.

And the people said unto Joshua, The LORD our God will we serve, and his voice will we obey.

So Joshua made a covenant with the people that day, and set them a statute and an ordinance in Shechem.

And Joshua wrote these words in the book of the law of God, and took a great stone, and set it up there under an oak, that was by the sanctuary of the LORD.

And Joshua said unto all the people, Behold, this stone shall be a witness unto us; for it hath heard all the words of the LORD which he spake unto us: it shall be therefore a witness unto you, lest ye deny your God.
