Exodus 38:5

2 And he made the horns thereof upon the four corners of it; the horns thereof were of one piece with it: and he overlaid it with brass.

3 And he made all the vessels of the altar, the pots, and the shovels, and the basins, the flesh-hooks, and the firepans: all the vessels thereof made he of brass.

4 And he made for the altar a grating of network of brass, under the ledge round it beneath, reaching halfway up.

5 And he cast four rings for the four ends of the grating of brass, to be places for the staves.

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

7 And he put the staves into the rings on the sides of the altar, wherewith to bear it; he made it hollow with planks.

8 And he made the laver of brass, and the base thereof of brass, of the mirrors of the ministering women that ministered at the door of the tent of meeting.
