'Joined' in the Bible

Two tenons shall there be in each board, joined one to another: thus shalt thou make for all the boards of the tabernacle.

It shall have two shoulder-pieces joined to the two ends thereof, that it may be joined together.

Each board had two tenons, joined one to another: thus did he make for all the boards of the tabernacle.

They made shoulder-pieces for it, joined together; at the two ends was it joined together.
