Exodus 38:4

2He made its horns on its four corners. Its horns were of one piece with it, and he overlaid it with bronze.

3He made all the vessels of the altar: the pots, the shovels, the basins, the forks, and the fire pans. He made all its vessels of bronze.

4He made for the altar a grating of a network of bronze, under the ledge around it beneath, reaching halfway up.

5He cast four rings for the four corners of bronze grating, to be places for the poles.

6He made the poles of acacia wood, and overlaid them with bronze.
