And they shall make an ark of shittim wood: two cubits and a half shall be the length thereof, and a cubit and a half the breadth thereof, and a cubit and a half the height thereof.
Treasury of Scripture
an ark. Aron denotes a chest, or coffer, in general; but is applied particularly to the chest or ark in which the testimony or two tables of the covenant were laid up; on the top of which was the propitiatory or mercy seat; and at the end of which were the cherubim of gold; between whom the visible sign of the presence of God appeared as seated upon his throne.
