Joshua 8:32-33

32And there, in the presence of the people of Israel, he wrote on the stones a copy of the law of Moses, which he had written.

33And all Israel, sojourner as well as native born, with their elders and officers and their judges, stood on opposite sides of the ark before the Levitical priests who carried the ark of the covenant of the Lord, half of them in front of Mount Gerizim and half of them in front of Mount Ebal, just as Moses the servant of the Lord had commanded at the first, to bless the people of Israel.
