43:14 From the base of the ground to the lower edge is 3½ feet, and the width 1¾ feet; and from the smaller ledge to the larger edge, 7 feet, and the width 1¾ feet; 43:15 and the altar hearth, 7 feet, and from the altar hearth four horns projecting upward. 43:16 Now the altar hearth is a perfect square, 21 feet long and 21 feet wide.
