'Hand breadth' in the Bible

And behold, there was a wall on the outside of the house round about, and in the man's hand a measuring-reed of six cubits, each of one cubit and a hand breadth. And he measured the breadth of the building, one reed; and the height, one reed.

And the double hooks of a hand breadth were fastened round about within; and upon the tables they put the flesh of the offering.

And these are the measures of the altar in cubits: the cubit is a cubit and a hand breadth. The bottom was a cubit in height and the breadth a cubit, and its border on the edge thereof round about, one span: and this was the base of the altar.
