Exodus 38:7

4 And he made a network of brass for the altar, under the frame round it, stretching half-way up;

5 And four rings for the four angles of this network, to take the rods.

6 The rods he made of hard wood plated with brass.

7 He put the rods through the rings at the opposite sides of the altar for lifting it; he made the altar hollow, boarded in with wood.

8 And he made the washing-vessel of brass on a brass base, using the polished brass looking-glasses given by the women who did work at the doors of the Tent of meeting.

9 To make the open space, he put hangings on the south side, of the best linen, a hundred cubits long:

10 Their twenty pillars and their twenty bases were brass; and the hooks of the pillars and their bands were of silver.
