   All four occurrences use the form as a proper noun for the same mountain. In Deuteronomy 11:29 the APB renders the instruction to set the blessing there; in Deuteronomy 27:12 it renders tribes standing there to bless the people; in Joshua 8:33 it describes half the people standing opposite it; and in Judges 9:7 it places Jotham on its top as he calls out.

In the Anselm Project Bible: The APB consistently presents the proper name as "Mount Gerizim" in all four verses. This identifies its presentation of the clause rather than a separate lexical rendering claim.
