American Standard Version

²² Each board had two tenons, ^[a]joined one to another: thus did he make for all the boards of the tabernacle. ²³ And he made the boards for the tabernacle: twenty boards for the south side southward; ²⁴ and he made forty sockets of silver under the twenty boards; two sockets under one board for its two tenons, and two sockets under another board for its two tenons.
