Adam Clarke on Judges 9:21

Went to Beer - Mr. Maundrell, in his journey from Aleppo to Jerusalem, p. 64, 5th edit., mentions a place of this name, which he thinks to be that to which Jotham fled, and supposed to be the same as Mishmash, 1Sam 14:5, 1Sam 14:31. It is situated, he says, towards the south, on an easy declivity; and has a fountain of excellent water at the bottom of the hill from which it has taken its name.
