15-25 “Frame The Dwelling with planks of acacia wood, each section of frame fifteen feet long and two and one-quarter feet wide, with two pegs for securing them. Make all the frames identical: twenty frames for the south side with forty silver sockets to receive the two pegs from each of the twenty frames; the same construction on the north side of The Dwelling; for the rear of The Dwelling, which faces west, make six frames with two additional frames for the rear corners. Both of the two corner frames need to be double in thickness from top to bottom and fit into a single ring—eight frames altogether with sixteen sockets of silver, two under each frame.
