Deuteronomy 11:29

“So it will be when you cross the Jordan, you shall set up on Mount Ebal, these stones, as I am commanding you today, and you shall coat them with lime.

“When you cross the Jordan, these shall stand on Mount Gerizim to bless the people: Simeon, Levi, Judah, Issachar, Joseph, and Benjamin.

And all Israel with their elders and officers and their judges were standing on both sides of the ark before the Levitical priests who carried the ark of the covenant of Yahweh, the sojourner as well as the native. Half of them stood in front of Mount Gerizim and half of them in front of Mount Ebal, just as Moses the servant of Yahweh had given a command at first to bless the people of Israel.

Then they told Jotham, so he went and stood on the top of Mount Gerizim and lifted his voice and called out. Thus he said to them, “Listen to me, O lords of Shechem, that God may listen to you.

“Our fathers worshiped on this mountain, and you people say that in Jerusalem is the place where men ought to worship.”
