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.

2276. 'Perhaps thirty will be found [there]' means some existence of conflict. This is clear from the meaning of the number 'thirty'. The reason 'thirty' means some existence of conflict, thus a small amount of conflict, is that this number is the product of 'five', meaning that which is small, times 'six', meaning toil or conflict, as shown in Volume One, in 649, 720, 737, 900, 1709.

[2] Hence also that number, wherever one reads it in the Word, means something relatively small, as in Zechariah,

I said to them, If it is good in your eyes, give me my wages; and if not, withhold them. And they weighed out my wages, thirty pieces of silver. And Jehovah said to me, Throw it to the potter, the magnificent price I was valued at among them. And I took the thirty pieces of silver and threw it into the house of Jehovah, to the potter. Zechariah 11:12-13.

This stands for how small a value those people placed on the Lord's merit, and on redemption and salvation from Him. 'The poster' stands for reformation and regeneration.

[3] This explains the reference to the same thirty pieces of silver in Matthew,

They took the thirty pieces of silver, the price set on him whom they had bought from the children of Israel, and gave them for the potter's field, as the Lord commanded me. Matthew 27:9-10.

From these words it is quite clear that 'thirty' here stands for the small price set on him. A slave, who was not considered to be worth much, was valued at thirty shekels, as is clear in Moses,

If the ox gores a slave or a servant-girl, the owner shall give to his master thirty shekels of silver; and the ox shall be stoned. Exodus 21:32.

How little a slave was considered to be worth is clear from verses 20-21, of that same chapter. In the internal sense 'a slave' stands for toil.

[4] The reason Levites were called upon for ministerial duty - which is described as one 'coming to perform military service and to do the work in the tent [of meeting] - from thirty up to fifty years of age', Numbers 4:3, 23, 30, 35, 39, 43, was that 'thirty' means those who were beginners, thus those who as yet could perform little of what was meant in the spiritual sense by 'military service'.

[5] There are other places in the Word besides these where 'thirty' is mentioned, such as in the requirement that with a young bull a minchah of three tenths [of fine flour] was to be offered by them, Numbers 15:9. Such was required because the sacrifice of an ox represented natural good, as shown above in 2180, and natural good is small in comparison with spiritual good, which was represented by the sacrifice of a ram, and smaller still in comparison with celestial good, which was represented by the sacrifice of a lamb, with which sacrifices a different number of tenths to the minchah were required, as is clear in verses 4-6 of that chapter, and also in Numbers 28:12-13, 20-21, 28-29; 29:3-4, 9-10, 14-15. These differing numbers of tenths, or proportions, would never have been commanded if they had not embodied heavenly arcana within them.

[6] 'Thirty' again stands for that which is small 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.

'Thirty' stands for a small yield and for that which has laboured to only a small extent. Those numbers would not have been specified unless they had embodied the things meant by them.
