The breadth of the entry: it is meant of the whole length of the entry, or walk through the porch, which was so wide, and to which they ascended by stairs of a semi-circular form. The length; the height is meant, but it is called its length, either because height is an erected length, or rather because thirteen cubits is the greater dimension; and this interpreters agree in, it is the height of the gate here measured.
