Exodus 38:6 WEB

⁴  He made for the altar a grating of a network of brass, under the ledge around it beneath, reaching halfway up.

⁵  He cast four rings for the four ends of brass grating, to be places for the poles.

⁶  He made the poles of acacia wood, and overlaid them with brass.

⁷  He put the poles into the rings on the sides of the altar, with which to carry it. He made it hollow with planks.

⁸  He made the basin of brass, and its base of brass, out of the mirrors of the ministering women who ministered at the door of the tent of meeting.
