'Thirty' has a twofold significance because it is is the product of five and six, and also three and ten. From five multiplied by six, it signifies some aspect of combat, because 'five' signifies some part or aspect, and 'six,' combat. From three multiplied by ten, it signifies something full of remains of good and truth, because 'three' signifies fullness, and 'ten,' remains of good and truth. A composite number involves the same as the simple numbers it has as its factors.

This is clear from the representation of the sons of Israel, to whom his 'brothers' refers here, as spiritual truths within the natural, dealt with just above in 6040; from the meaning of 'father's house' as the forms of good there, also dealt with just above, in 6041; from the meaning of 'the land of Canaan' as the Church, dealt with in 3686, 3705, 4447, 4517, 5136; and from the meaning of 'coming' to Joseph, or to Egypt where Joseph was, as being introduced into the Church's factual knowledge, dealt with above in 6004, 6018. Regarding the introduction of the truths the Church possesses into the factual knowledge present in the natural, see above in 6023, and regarding the joining together of them, below in 6047.
