7842. 'Until the fourteenth of the month' means leading up to a holy state. This is clear from the meaning of 'the fourteenth day' as a holy state. 'Day' means a state, see above in 7831, while 'fourteen' has the same meaning as seven, and 'seven' means what is holy, see 395, 433, 716, 881, 5265, 5268. For multiple numbers have meanings similar to those of their factors, 5291, 5335, 5708. This explains why the Passover had to begin on the fourteenth day of the month, continue for seven days, and end on the twenty-first day, which too means what is holy, because that number is the product of three multiplied by seven. That was why there had to be a holy convocation on the first day of the Passover, and a holy convocation on the twenty-first day [of the month], verse 16.

881. 'Seven' means that which is holy because now charity is the subject. This is clear from the meaning of the number seven, dealt with already in 395, 716. Furthermore 'seven' has been brought in here so that all things may be linked together as though they were historical events, for in the internal sense 'seven' and 'seven days' contribute nothing more to the meaning than a certain holiness which this second state possesses from what is celestial, that is, from charity.
