Exodus 38:5

2 and he maketh its horns on its four corners; its horns have been of the same; and he overlayeth it with brass;

3 and he maketh all the vessels of the altar, the pots, and the shovels, and the sprinkling-pans, the forks, and the fire-pans; all its vessels he hath made of brass.

4 And he maketh for the altar a brazen grate of net-work, under its border beneath, unto its midst;

5 and he casteth four rings for the four ends of the brazen grate -- places for bars;

6 and he maketh the staves of shittim wood, and overlayeth them with brass;

7 and he bringeth in the staves into the rings on the sides of the altar, to bear it with them; hollow [with] boards he made it.

8 And he maketh the laver of brass, and its base of brass, with the looking-glasses of the women assembling, who have assembled at the opening of the tent of meeting.
