Joshua 8:32 (NIV) There, in the presence of the Israelites, Joshua wrote on stones a copy of the law of Moses. After experiencing all the powerful moves of God, God commands Joshua to write the Words of God on two stone altars built on Mount Gerizim and Mount Ebal. God is demonstrating we need to keep embracing the Word of God. This was not an on-the-spot decision. This command was given Deuteronomy 28. Now it is fulfilled in Joshua C. 8. God knew the people needed a visible recording of the Word of God that they all could read and rehearse. Nothing fancy here! Just the Word!
