Arcana Coelestia # 9597
9597. 'With cherubs' means the Lord's watchfulness, guarding it from the approach of the hells and the harm they can do. This is clear from the meaning of 'cherubs' as watchfulness and providence, preventing any approach to the Lord except through good and protecting from harm the good from the Lord which exists in heaven and with man, dealt with in 9509, consequently guarding heaven from the approach of the hells and the harm they can do.
Genesis 1:6-8
6
God said, "Let there be an expanse in the middle of the waters, and let it divide the waters from the waters."
7
God made the expanse, and divided the waters which were under the expanse from the waters which were above the expanse; and it was so.
8
God called the expanse "sky." There was evening and there was morning, a second day.
