JOS 8:33

33 The Israeli leaders, the officials, the judges, and other Israelis were there, standing nearby. Many people who were not Israelis were also there. Half of the people stood [on one side of the valley] below Ebal Mountain, and the other half of the people stood [on the other side of the valley] below Gerizim Mountain. The sacred chest was [in the valley] between the two groups. That was what Moses had previously commanded that the people should do when [Yahweh was about to] bless them.
