7900. 'In the first [month], on the fourteenth day of the month' means at the beginning of a holy state. This is clear from the meaning of 'in the first' as the beginning, as above in 7887, 7891; and from the meaning of 'the fourteenth day' as a holy state. For the meaning of the number fourteen as what is holy, see above in 7842; and for 'day' as state, 7881. The reason why fourteen means what is holy is that it arises from seven, and where seven is mentioned in the Word what is holy is meant. For the meanings held by simple numbers are much the same as those held by compound ones, 5291, 5335, 5708. Since the Passover was the holiest of feast days, it was laid down that it should be celebrated on the fourteenth day of the month, last seven days, and be brought to an end on the twenty-first day, which also means what is holy. It was therefore also established that those who were unable to celebrate the Passover in the first month should do so the following month, likewise on the fourteenth day. This provision is stated in Moses as follows,

When any man is unclean because of a dead body, ¹ or is on a journey far away, among you or your descendants, ² he shall still keep the Passover to Jehovah. In the second month, on the fourteenth day between the evenings they shall keep it. Numbers 9:10-11.

7887. 'Even on the first day you shall remove yeast from your houses' means that there must be no falsity whatever in good. This is clear from the meaning of the first 'day' as the beginning of that state, day' being state, see just above in 7881; from the meaning of 'yeast' as falsity, dealt with below; and from the meaning of 'house' as good, dealt with in 2233, 2134, 2559, 3652, 3720, 7833-7835, 7848. From these meanings it is evident that 'on the first day you shall remove yeast from your houses' means that from the very beginning of that state there must be no falsity whatever in good. So far as good is concerned, the forms of it are unendingly various; and they derive their specific quality from truths. Consequently the good has the same quality as the truths that enter it. The truths that enter are rarely genuine. Instead they are appearances of truth, and also falsities, though not however opposites of truths. Even so, when these falsities enter good - which happens when a person leads a life in accordance with them - as a result of ignorance, ignorance that has innocence within it, and when the person's end in view is that of doing good, they are regarded by the Lord and in heaven not as falsities but as the equivalents of truth. And according to the character of the person's innocence they are accepted as truths. Such is the way that good obtains its specific quality. From all this one may recognize what is meant by the explanation that there must be no falsity whatever in good.
