The commandments of the Decalogue are called the ten words or ten commandments, because "ten" signifies all; consequently the ten words mean all things of the Word, and thus all things of the church in brief. All things of the Word and all things of the church in brief are meant, because there are in each commandment three interior senses, each sense for its own heaven, for there are three heavens. The first sense is the spiritual moral sense; this is for the first or outmost heaven; the second sense is the celestial spiritual sense, which is for the second or middle heaven; and the third sense is the Divine celestial, which is for the third or inmost heaven. There are thus three internal senses in every least particular of the Word. For from the Lord, who is in things highest, the Word has been sent down in succession through the three heavens even to the earth, and thus has been accommodated to each heaven; and therefore the Word is in each heaven and I may say in each angel in its own sense, and is read by them daily; and there are preachings from it, as on the earth. For the Word is Divine truth itself, thus Divine wisdom, going forth from the Lord as a sun, and appearing in the heavens as light. Divine truth is the Divine that is called the Holy Spirit, for it not only goes forth from the Lord but it also enlightens man and teaches him, as is said of the Holy Spirit. As the Word in its descent from the Lord has been adapted to the three heavens, and the three heavens are joined together as inmosts are with outmosts through intermediates, so, too, are the three senses of the Word; which shows that the Word is given that by it there may be a conjunction of the heavens with each other, and a conjunction of the heavens with the human race, for whom the sense of the letter is given, which is merely natural and thus the basis of the other three senses. That the ten commandments of the Decalogue are all things of the Word in brief can be seen only from the three senses of those commandments, which are as above stated. (A.E., n. 1024). What these three senses in the commandments of the Decalogue are can be seen from the following summary explanation. The first commandment, "Thou shalt not worship other gods beside Me," involves in the spiritual moral sense that nothing else nor anyone else is to be worshipped as Divine; nothing else, that is, Nature, by attributing to it something Divine of itself; nor anyone else, that is, any vicar of the Lord or any saint. In the celestial spiritual sense it involves that one God only is to be acknowledged, and not several according to their qualities, as the ancients did, and as some heathens do at this day, or according to their works, as Christians do at this day, who make out one God because of creation, another because of redemption, and another because of enlightenment.
