9637. 'And a cubit and a half the breadth of one board' means the truth derived from it, a sufficient amount to effect a joining together. This is clear from the meaning of 'one and a half' as that which is complete, dealt with in 9487-9489, thus also a sufficient amount, this being something complete. The reason why that truth is derived from it - from the good, meant by the boards made from shittim wood, 9634, 9635 - is that every form of good has its own truth, and every truth has its own good. Good without truth cannot be seen, and truth without good cannot have any real existence; for truth gives shape to good, and good gives truth its being. The shape that good is given enables it to be seen, and the being that truth is given enables it to have real existence. They are like flame and light. A flame without light cannot be seen; therefore it sends out light to allow itself to be seen; and the light without the flame cannot have any existence. The situation is the same with the human will and its understanding. The will cannot be seen without the understanding, and the understanding has no existence without the will. The situation with love and faith too is very similar to that with good and truth, or flame and light, or will and understanding. For all good belongs to love, and all truth to faith rooted in love; and the human will is dedicated to the reception of the good belonging to love, and the understanding to the reception of the truth belonging to faith. Also the flame or fire of life is love, and the light of life is faith.
