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.
