Parallel
Exodus 26:17
Brenton's English Septuagint · Berean Standard Bible
Two joints shalt thou make in one post, answering the one to the other: so shalt thou do to all the posts of the tabernacle.
Two tenons (note: That is, projecting pieces of wood made for insertion into another piece; similarly in verse 19.) must be connected to each other for each frame. Make all the frames of the tabernacle in this way.
