Exodus 38:3-5

New King James Version

³ He made all the utensils for the altar: the pans, the shovels, the basins, the forks, and the firepans; all its utensils he made of bronze. ⁴ And he made a grate of bronze network for the altar, under its rim, midway from the bottom. ⁵ He cast four rings for the four corners of the bronze grating, as holders for the poles.
