'Cubit' in the Bible

“You shall make a table of acacia wood, two cubits long and one cubit wide and one and a half cubits high.

The cubit on one side and the cubit on the other, of what is left over in the length of the curtains of the tent, shall lap over the sides of the tabernacle on one side and on the other, to cover it.

Its length shall be a cubit, and its width a cubit, it shall be square, and its height shall be two cubits; its horns shall be of one piece with it.

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

Then he made the altar of incense of acacia wood: a cubit long and a cubit wide, square, and two cubits high; its horns were of one piece with it.
