Charles H. Spurgeon on Psalms 104:16

Full of sap. The cedar has a store of resin. It flows from wounds made in the bark, and from the scales of the cones, and is abundant in the seeds. Both the resin and the wood were much valued by the ancients. The Romans believed that the gum which exuded from the cedar had the power of rendering whatever was steeped in it incorruptible; and we are told that the books of Numa, the early king of Rome, which were found uninjured in his tomb, five hundred years after his death, had been steeped in oil of cedar. The Egyptians also used the oil in embalming their dead. Mary and Elizabeth Kirby, in "Chapters on Trees," 1873.
