'Foot breadth' in the Bible

attack them not; for I will not give you of their land, no, not so much as a foot-breadth; for I have given mount Seir as a possession unto Esau.

And He gave him no inheritance in it, no, not even a foot-breadth. And He promised that He would give it to him for a possession, and to his seed after him, there being no child to him.
