And the lot of the tribe of the children of Judah according to their families was: to the border of Edom, the wilderness of Zin, southward, in the extreme south.

And the south side was from the extreme end of Kirjath-jearim, And the border went out on the west, And went out to the spring of the waters of Nephtoah.

And Saul abode at the extreme end of Gibeah under the pomegranate-tree which was in Migron; and the people that were with him were about six hundred men.
