Exodus 38:4 DBY

²  And he made its horns on the four corners thereof; its horns were of itself; and he overlaid it with copper.

³  And he made all the utensils of the altar: the pots, and the shovels, and the bowls, the forks, and the firepans; all its utensils made he of copper.

⁴  And he made for the altar a grating of network of copper under its ledge from beneath, to the very middle of it.

⁵  And he cast four rings for the four corners of the grating of copper, as receptacles for the staves.

⁶  And he made the staves of acacia-wood, and overlaid them with copper.
