Here are the facts as I see them. For four hundred years Israel had dwelt in Egypt, surrounded by the crassest idolatry. By the hand of Moses they were brought out at last and started toward the land of promise. The very idea of holiness had been lost to them. To correct this, God began at the bottom. He localized Himself in the cloud and fire and later when the tabernacle had been built He dwelt in fiery manifestation in the Holy of Holies. By innumerable distinctions God taught Israel the difference between holy and unholy. There were holy days, holy vessels, holy garments. There were washings, sacrifices, offerings of many kinds. By these means Israel learned that God is holy . It was this that He was teaching them. Not the holiness of things or places, but the holiness of Jehovah was the lesson they must learn.
