Deuteronomy 27:12-13

After you cross the Jordan River, you will go to Mount Gerizim and Mount Ebal. The tribes of Simeon, Levi, Judah, Issachar, Ephraim, Manasseh, and Benjamin will go up on Mount Gerizim, where they will bless the people of Israel. The tribes of Reuben, Gad, Asher, Zebulun, Dan, and Naphtali will go up on Mount Ebal where they will agree to the curses.
