And not alone the creatures on earth, even the angels thought Adam the lord of all, and they were about to salute him with "Holy, holy, holy, is the Lord of hosts," when God caused sleep to fall upon him, and then the angels knew that he was but a human being.
The purpose of the sleep that enfolded Adam was to give him a wife, so that the human race might develop, and all creatures recognize the difference between God and man. When the earth heard what God had resolved to do, it began to tremble and quake. "I have not the strength," it said, "to provide food for the herd of Adam's descendants. "But God pacified it with the words, "I and thou together, we will find food for the herd." Accordingly, time was divided between God and the earth; God took the night, and the earth took the day. Refreshing sleep nourishes and strengthens man, it affords him life and rest, while the earth brings forth produce with the help of God, who waters it. Yet man must work the earth to earn his food.
