'Extreme' in the Bible

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.

The cities of the tribe of the sons of Judah in the extreme south toward the border of Edom were Kabzeel and Eder and Jagur,

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.
