'Hand breadth' in the Bible

And behold a wall on the outside of the house around, and in the man's hand a measuring reed of six cubits long by the cubit and a hand-breadth: so he measured the breadth of the building, one reed: and the hight, one reed.

And these are the measures of the altar after the cubits: The cubit is a cubit and a hand-breadth; even the bottom shall be a cubit, and the breadth a cubit, and the border of it by its edge around shall be a span: and this shall be the higher place of the altar.
