The unit of the Hebrew system of measurement. The common cubit is the distance from the elbow to the end of the middle finger; the sacred cubit is a full yard long. Cubits are mentioned in 3Kings, 7, and 2Paralipomenon, 3; in the former the two brass columns in Solomon's Temple are said to be 18 cubits high; in the latter, 35. It is said that the cubit which Noe used when he built the ark equalled six common cubits; this is called a geometrical cubit.
