And for the second side of the tabernacle on the north side [there shall be] twenty boards:
And for the second side of the tabernacle the north side,…. The direction of the tabernacle was east and west; at the east end was the entrance into the holy place, and at the west end the holy of holies; and the two sides were north and south; and as on the south side, so on the north
[there shall be] twenty boards: just the same number as the laws of building required.
