'Hand breadth' in the Bible

And behold, there was a wall on the outside of the temple all around, and in the man’s hand was a measuring rod of six cubits, each of which was a cubit and a handbreadth. So he measured the thickness of the wall, one rod; and the height, one rod.

The double hooks, one handbreadth in length, were installed in the house all around; and on the tables was the flesh of the offering.

“And these are the measurements of the altar by cubits (the cubit being a cubit and a handbreadth): the base shall be a cubit and the width a cubit, and its border on its edge round about one span; and this shall be the height of the base of the altar.
