The third and fourth commandments of the Decalogue contain things that must be done, namely, that the Sabbath must be kept holy, and that parents must be honored. The other commandments contain things that are not to be done, namely, that other gods must not be worshipped; that the name of God must not be profaned; that one must not steal, must not commit adultery, must not bear false witness, must not covet the goods of others. These two commandments are commandments to be done because the sanctification of the rest of the commandments depends upon these, for the "Sabbath" signifies the union in the Lord of the Divine itself and the Divine Human, also His conjunction with heaven and the church, and thus the marriage of good and truth in the man who is being regenerated. This being the signification of the Sabbath, it was the chief representative of all things of worship in the Israelitish Church, as is evident in Jeremiah (xvii. 20-27), and elsewhere. It was the chief representative of all things of worship, because the first thing in all things of worship is the acknowledgment of the Divine in the Lord's Human, for without that acknowledgment man can believe and do only from self, and to believe from self is to believe falsities, and to do from self is to do evils, as is also evident from the Lord's words in John: To those asking, "What shall we do that we might work the works of God?" Jesus said, "This is the work of God, that ye believe on Him whom God hath sent" (vi. 28, 29). And in the same, "He that abideth in Me and I in him, the same beareth much fruit; for apart from Me ye can do nothing" (xv. 5).
