'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.

2166. 'That you may refresh yourselves' means insofar as it is in keeping. This is not so clear from the proximate meaning of these words in the internal sense, though it is nevertheless clear from the whole train of thought. The subject here is Divine perception - that it might draw nearer to the perception possessed by the Lord's human as it was at that time, and that it might bring itself down nearer to His intellectual concepts, by taking on something natural, and also something heavenly or celestial to go with that something natural, insofar as it is in keeping, meant by 'refreshing oneself'. In the proximate sense 'refreshing oneself by means of bread' means being revived, and so enjoying what little of the celestial is in keeping.
