The Tenons

Two tenons shall there be in one board, set in order one against another: thus shalt thou make for all the boards of the tabernacle, ver. 17.), “Two tenons,” Hebrew, “hands.” According to their name they appear to represent the hands of faith, laying hold on the redemption, which is In Christ Jesus; and, according to their position at the bottom of the boards, they suggest the idea, of the feet, of faith, standing firm on redemption, and the redemption price.
“Set in order.” So as to fit exactly into the sockets. No slackness, no wavering, but “steadfast, and unmoveable,” “stablished, strengthened, settled:” “Two hands,” or two feet. A firm grasp, and firm standing. Thus shalt ‘thou make for all’ the boards of the tabernacle. The, tabernacle of God is composed of such and such only as have saving faith in Jesus; and in: the redemption accomplished by his atoning blood.
