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.

9 And he maketh the court; at the south side southward, the hangings of the court of twined linen, a hundred by the cubit,

10 their pillars [are] twenty, and their brazen sockets twenty, the pegs of the pillars and their fillets [are] silver;

11 and at the north side, a hundred by the cubit, their pillars [are] twenty, and their sockets of brass twenty; the pegs of the pillars and their fillets [are] silver;
