429. And I heard the number of them that were sealed.- That this signifies the quality of those who are in good, and separated from the evil, is evident from the signification of number, which denotes the quality of the thing treated of, with which signification we shall deal presently; and from the signification of the sealed, as denoting those who are in good, distinct and separate from others. Concerning which signification see just above (n. 427:1).

Number and measure are mentioned in many places in the Word, and it is supposed that nothing more is meant by these than number and measure; but by number and measure in the spiritual sense is meant the quality of the thing treated of. The quality itself is determined by the numbers expressed, as in this place by a hundred and forty and four thousand, and afterwards by twelve thousand out of every tribe. The signification of these numbers shall therefore be explained in the following article. The reason why number signifies the quality of the thing treated of, is that the Word is spiritual, and consequently every detail contained in it is spiritual, and spiritual things are not numbered and measured, but yet they fall into numbers and measures when they [descend] out of the spiritual world, or out of heaven, where angels are, into the natural world or earth, where men are; and similarly, when they pass out of the spiritual sense of the Word in which angels are, into the natural sense of the Word in which men are. The natural sense of the Word is the sense of its letter. This is the reason that in this sense there are numbers, and that they signify spiritual things, or such as relate to heaven and the church. It has been often shown me that the spiritual things of heaven, such as those which the angels think and speak, also fall into numbers. When they were conversing, their discourse fell into pure numbers, and these were seen upon paper; they afterwards said that it was their discourse which had fallen into numbers, and that those numbers in a series contained everything they uttered. I was also instructed as to their signification, and how they were to be understood; upon this subject we shall have frequent occasion to speak in the following pages. But concerning writings from heaven in pure numbers, see Heaven and Hell 263). That all numbers in the Word signify things pertaining to heaven and the church, see also above (n. 203, 336).

5335. 'And Joseph was a son of thirty years' means a state when the quantity of remnants was complete. This is clear from the meaning of 'thirty' as a completed number of remnants, dealt with below, and from the meaning of 'years' as states, dealt with in 482, 487, 488, 493, 893. In the Word the number thirty can mean some existence of conflict, or else it can mean a completed number of remnants. The reason why that number has this twofold meaning is that it is arrived at by multiplying five and six, or else by multiplying three and ten. When it is the product of five times six it means some existence of conflict, 2276, because 'five' means some, 649, 4638, 5291, and 'six' conflict, 720, 737, 900, 1709. But when thirty is the product of three times ten it means a completed number of remnants, because 'three' means that which is complete, 2788, 4495, and 'ten' means remnants, 576, 1906, 2284. A composite number implies much the same as the simple ones of which it is the product, 5291. Remnants are the truths joined to good which have been stored away by the Lord in a person's interior parts, see 468, 530, 560, 561, 576, 660, 1050, 1738, 1906, 2284, 5135.

[2] A completed number of remnants is likewise meant by 'thirty' - as it is also by 'sixty', and by 'a hundred' too - in Mark,

The seed which fell into good ground yielded fruit growing up and increasing. One bore thirty-fold, and another sixty, and another a hundred. Mark 4:8, 10.

Each of these numbers, being a multiple of ten, means a completed number of remnants. Also, because no one can be regenerated - that is, permitted to enter into spiritual temptations, by means of which regeneration is effected - until he has received a completed number of remnants, it was therefore laid down that no Levite should carry out any work in the tent of meeting until he was fully thirty years old. Their work or function is also called 'military service', being referred to in Moses as follows,

Take a census of the sons of Kohath from the midst of the sons of Levi - from sons thirty years of age and over, up to sons fifty years of age, everyone coming to perform military service, to do the work in the tent of meeting. Numbers 4:2-3.

Much the same is said regarding the sons of Gershon, and much the same regarding the sons of Merari, in verses 22, 23, 29, 30, and then in verses 35, 39, 43. Of that same chapter in Moses. And something similar is implied where it says that David began to reign when he was a son thirty years of age, 2 Samuel 5:4.

[3] From all this one may now see why the Lord did not make Himself known until He was thirty years of age, Luke 3:23. At that age a completed number of remnants existed with Him, though these remnants which the Lord possessed were ones that He Himself had acquired for Himself. They were also Divine ones and the means by which He united His Human Essence to His Divine Essence and made that Human Essence Divine, 1906. In Him therefore lies the reason why 'thirty years' means a state when the quantity of remnants is complete and why the priests the Levites began to perform their specific functions when they were thirty years old. And because he was to represent the Lord's kingship, David did not begin to reign until he was that same age. For every representative is derived from the Lord, and therefore every representative has reference to Him.
