Joshua 8:32-33

32And he wrote there upon the stones a copy of the law of Moses, which he wrote, in the presence of the children of Israel.

33And all Israel, and their elders and officers, and their judges, stood on this side the ark and on that side before the priests the Levites, which bare the ark of the covenant of the LORD, as well the stranger as the homeborn; half of them in front of mount Gerizim, and half of them in front of mount Ebal; as Moses the servant of the LORD had commanded, that they should bless the people of Israel first of all.
