In Exodus 20:8-10, Deuteronomy 5:12-13, in the spiritual meaning, the third commandment refers to our being reformed and regenerated by the Lord. The six days of labor mean battling against the flesh and its cravings and also against the evils and falsities that are in us from hell. The seventh day means our becoming connected to the Lord and our being regenerated as a result. (True Christian Religion 302)

41. Anything that is man's own has no life in it; and when depicted visually it looks like something hard as a bone and black. But anything that comes from the Lord does contain life. It has that which is spiritual and celestial within it, and when depicted visually it looks human and alive. It is perhaps incredible, but nevertheless absolutely true, that every expression, every idea, and every least thought of an angelic spirit is alive. In even the most detailed areas of his thought there is an affection that comes from the Lord, who is life itself. Consequently all that derives from the Lord has life within it, for it contains faith in Him, and is here meant by 'a living creature'. It then has the outward appearance of a body, meant here by that which is moving, or creeping. To man these matters remain arcana, but since the subject here is the living and moving creature, they ought at least to be mentioned here.
