Ezekiel 43:14

The bottom - The basement just described is now called “the bottom upon the ground.” The altar (independently of the bottom) was composed of two stages called “settles,” the base of the “upper settle” (M) being less than that of the “lower” (L).

To the lower settle - That is, to the top of “the lower settle,” which was to be “two cubits high.”

From the lesser settle ... to the greater settle - i. e., from the top of the “lower settle” to the top of the “upper settle,” called “lesser” and “greater,” because the height of the lower is less than that of the “upper; The breadth” here is the part of the lower settle not covered by the upper settle, projecting one cubit on every side.
