Gerizim

And when the Lord thy God shall have brought thee into the land, whither thou goest to dwell, thou shalt put the blessing upon mount Garizim, the curse upon mount Hebal:

These shall stand upon mount Garizim to bless the people, when you are passed the Jordan: Simeon, Levi, Juda, Issachar, Joseph, and Benjamin.

And all the people, and the ancients, and the princes, and judges, stood on both sides of the ark, before the priests that carried the ark of the covenant of the Lord, both the stranger and he that was born among them, half of them by Mount Garizim, and half by Mount Hebal, as Moses the servant of the Lord, had commanded. And first he blessed the people of Israel.

This being told to Joatham, he went, and stood on the top of Mount Garizim: and lifting up his voice, he cried, and said: Hear me, ye men of Sichem, so may God hear you.
