Exodus 38:7-11

7And he put the poles through the rings on the sides of the altar to carry it with them. He made it hollow, with boards.

8He made the basin of bronze and its stand of bronze, from the mirrors of the ministering women who ministered in the entrance of the tent of meeting.

9And he made the court. For the south side the hangings of the court were of fine twined linen, a hundred cubits;

10their twenty pillars and their twenty bases were of bronze, but the hooks of the pillars and their fillets were of silver.

11And for the north side there were hangings of a hundred cubits; their twenty pillars and their twenty bases were of bronze, but the hooks of the pillars and their fillets were of silver.
