Amplified Bible

³¹ Bezalel made bars of acacia wood, five for the [frame] boards of the one side of the tabernacle, ³² and five bars for the boards of the tabernacle’s other side, and five bars for the boards at the rear side to the west. ³³ And he made the middle bar pass through [horizontally] halfway up the boards from one end to the other.
