Exodus 26:17 - Exposition

Two tenons . Literally, "hands." Projecting rods, such as those common in our dinner tables, seem to be meant. They may have been of metal, let into the boards to a certain depth, and projecting several inches beyond them. Or, possibly, they may have been of acacia wood. In one board — i.e. "In each board"—no doubt, at the bottom of each. Set in order one against the other. Arranged, i.e; at regular intervals, the position of each corresponding to the position of its fellow.
