Exodus 30:1-2

Wycliffe Bible

30 Also thou shalt make an altar of the wood of shittim, for to burn incense; (And thou shalt make an altar out of shittim wood, or acacia wood, on which to burn incense;)

² and the altar shall have a cubit of length, and another cubit of breadth, that is four-cornered, and two cubits in height; (and the) corners shall come forth of the altar. (and the altar shall be one cubit in length, and one cubit in breadth, that is, square, and two cubits in height; and horns shall come forth from the altar.)
