Exodus 36:27 YLT

²⁵  And for the second side of the tabernacle, for the north side, he hath made twenty boards,

²⁶  and their forty sockets of silver, two sockets under the one board, and two sockets under the other board;

²⁷  and for the sides of the tabernacle, westward, hath he made six boards;

²⁸  and two boards hath he made for the corners of the tabernacle, in the two sides;

²⁹  and they have been twins below, and together they are twins at its head, at the one ring; so he hath done to both of them at the two corners;
