Parallel
Exodus 30:2
Brenton's English Septuagint · Berean Standard Bible
And thou shalt make it a cubit in length, and a cubit in breadth: it shall be square; and the height of it shall be of two cubits, its horns shall be of the same piece.
It is to be square, a cubit long, a cubit wide, and two cubits high (note: The altar was approximately 1.5 feet in length and width, and 3 feet high (45.7 centimeters in length and width, and 91.4 centimeters high).). Its horns must be of one piece.
