Exodus 38:18-20

Young's Literal Translation

¹⁸ And the covering of the gate of the court [is] the work of an embroiderer, of blue, and purple, and scarlet, and twined linen; and twenty cubits [is] the length, and the height with the breadth five cubits, over-against the hangings of the court;

¹⁹ and their pillars [are] four, and their sockets of brass four, their pegs [are] of silver, and the overlaying of their tops and their fillets [are] of silver;

²⁰ and all the pins for the tabernacle, and for the court round about, [are] of brass.
