'Cubit' in the Bible

"You are to make a table of acacia wood, two cubits long, a cubit wide, and one and a half cubits high.

The half cubit that remain on either end of the length of the curtains of the tent is to hang over each side of the tent to cover it.

It is to be a square, one cubit long and one cubit wide, and it is to be two cubits high, with its horns of one piece with it.

Then he made a table of acacia wood two cubits long, one cubit wide, and one and a half cubits high.

He made the altar for burning incense of acacia wood, a square, one cubit long, one cubit wide, and two cubits high, with its horns of one piece with it.
