Joshua 8:32-33

32And he wrote there on the stones a copy of the law of Moses, which he had written before the children of Israel.

33And all Israel, and their elders, and their officers and judges, stood on this side and on that side of the ark before the priests the Levites, who bore the ark of the covenant of Jehovah, as well the stranger as the home-born [Israelite]; half of them toward mount Gerizim, and the other half of them toward mount Ebal; as Moses the servant of Jehovah had commanded, that they should bless the people of Israel, in the beginning.
