9437. And Moses was in the mountain forty days and forty nights. That this signifies what is complete in respect to instruction and influx, is evident from the signification of “forty,” as being what is full or complete. That “forty” denotes what is full or complete, is because “four” denotes what is full (see n. 9103), in like manner “ten” (n. 3107, 4638), and the number forty arises from four multiplied into ten; for multiplied numbers signify the same as the simple numbers from which they have been multiplied (n. 5291, 5335, 5708, 7973). (That all numbers in the Word signify real things, see n. 575, 3252, 4264, 4495, 4670, 5265, 6175.) It is from this then that Moses was in the mountain forty days and forty nights. That “forty” here signifies what is complete in respect to instruction and influx, is plain from what follows in chapters 25 to 32, in which are recounted the things concerning which he was instructed, which were the ark, Aaron, the Urim and Thummim, and the sacrifices. That “forty” signifies what is complete as to influx also, is because from that time Moses began to represent the holy external of the Word, which mediates between the Lord and the people; and mediation is effected by influx through this holy external into the representative in which the people were (see n. 9419).

[2] As “forty” signified what is full or complete, therefore Moses remained on Mount Sinai not only on this occasion, but also on another, “forty days and forty nights” (Exodus 34:28; Deuteronomy 9:18, 25; 10:10). And for this reason the sons of Israel wandered in the wilderness “forty years,” until, as it is said, “all that generation was consumed” (Numbers 14:33-34; 32:13). And for this reason it was said by Jonah to the Ninevites that “the city would be overthrown after forty days” (Jonah 3:4). And for this reason the prophet was commanded “to lie on the right side, and to bear the iniquity of the house of Judah forty days” (Ezekiel 4:6). For this reason also it is said of Egypt that it should be surrendered to “an utter solitude forty years, and after those years should be gathered together from the peoples” (Ezekiel 29:11-13). And for this reason “it rained upon the earth, so that it was inundated with a flood, forty days and forty nights” (Genesis 7:4, 12, 17). From this it is evident why it was decreed that a wicked man should be “beaten with forty stripes” (Deuteronomy 25:3); for “forty stripes” signified punishment to the full. From this it is also evident what is meant in the prophetic song of Deborah and Barak, that “there was neither shield nor spear seen in the forty thousands of Israel” (Judges 5:8); “in the forty thousands of Israel” denotes in all. It is evident also from this why the temple built by Solomon was “forty cubits long” (1 Kings 6:17); in like manner the new temple described in Ezekiel (41:2); for by “the temple,” in the supreme sense, is signified the Lord; in the internal sense, heaven and the church; and thus by “forty,” what is complete in respect to representation. In like manner in other passages.

5335. And Joseph was a son of thirty years. That this signifies a full state of remains, is evident from the signification of “thirty,” as being full of remains (of which below); and from the signification of “years,” as being states (see n. 482, 487, 488, 493, 893). The number “thirty” in the Word signifies somewhat of combat, and it also signifies full of remains. The reason why it has this twofold signification, is that it is composed of five and six multiplied together, and also of three and ten so multiplied. From five multiplied by six it signifies somewhat of combat (n. 2276), because “five” signifies somewhat (n. 4638, 5291), and “six” combat (n. 720, 730, 737, 900, 1709); but from three multiplied by ten it signifies full of remains, because “three” signifies what is full (n. 2788, 4495), and “ten” remains (n. 576, 1906, 2284); that a compound number involves the like as its components, see n. 5291. (That remains are the truths joined to good stored up by the Lord in man’s interiors, see n. 468, 530, 560, 561, 576, 660, 1050, 1738, 1906, 2284, 5135)

[2] A fullness of remains is signified also by “thirty,” by “sixty,” and by a “hundred,” in Mark:

The seed that fell into the good ground yielded fruit that sprang up and increased, and brought forth, one thirty, and another sixty, and another a hundred (Mark 4:8, 20);

as all these numbers arise from ten by multiplication, they signify a fullness of remains. And as man cannot be regenerated, that is, be admitted to the spiritual combats through which regeneration is effected, until he has received remains to the full, it was ordained that the Levites should not do any work in the tent of meeting until they had completed thirty years, which work or function is also called “warfare,” as we read in Moses:

Take the sum of the sons of Kohath from the midst of the sons of Levi, from a son of thirty years and upward to a son of fifty years, everyone that cometh to the warfare, to do the work in the tent of meeting (Numbers 4:2-3

Something similar is said of the sons of Gershon, and of the sons of Merari (Numbers 4:22-23, 29-30, 35, 39, 43). The like is involved in David’s being thirty years old when he began to reign (2 Samuel 5:4).

[3] From all this it is now plain why the Lord did not manifest Himself until He was thirty years of age (Luke 3:23); for He was then in the fullness of remains. But the remains the Lord had He Himself procured for Himself, and they were of the Divine; and by means of them He united the Human essence to the Divine essence, and made the Human essence Divine (n. 1906). From Him then it is that “thirty years” signify a full state as to remains, and that the priests the Levites entered upon their functions when they were thirty years old, and that David, because he was to represent the Lord as to the royalty, did not begin to reign until he was thirty; for every representative is derived from the Lord, and therefore every representative looks to the Lord.
