Exodus 38:2-4

Amplified Bible

² And he made its horns (horn-shaped projections) on the four corners of it; the horns were of one piece with it, and he overlaid it with bronze. ³ He made all the utensils and vessels of the altar [of burnt offering], the pots, shovels, basins [to catch the blood of the sacrificed animal], meat hooks and the firepans [to store live coals]. He made all its utensils of bronze. ⁴ He made for the altar a grating of bronze mesh under its rim, extending halfway up it.
