Exodus 38:3-5

Amplified Bible

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. ⁵ He cast four rings for the four corners of the bronze grating as holders for the carrying poles.
