Judges 9:21

And Jotham ran away, and fled, and went to Beer, and dwelt there, for fear of Abimelech his brother.

Jotham ran away, and fled. The moral of the parable he had spoken was this-That foolish and wicked men are found boldly usurping places of power and prominence, from the responsibility of which wise and good men are apt to shrink; and that the associates in such proceedings, where no regard is paid to principle or personal merit, will sooner or later fall by mutual destruction.

And went to Beer - the modern village el-Bireh, on the ridge which bounds the northern prospects of Jerusalem.
