Arcana Coelestia # 10656
10656. 'Seven days you shall eat the unleavened bread' means a holy state then, and making Divine Truth, purified from evil and from the falsities of evil, one's own. This is clear from the meaning of 'seven days' as a holy state from start to finish (states are meant by 'days', see 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850, that which is holy by 'seven', 395, 433, 716, 881, 5265, 5268, and a holy state from start to finish by 'seven days', 728, 6508, 9228, 10127); from the meaning of 'eating' as making one's own, dealt with in 3168, 3513(end), 3596, 4745; and from the meaning of that which is 'unleavened' as Divine Truth purified from evil and from the falsities of evil, dealt with in 9992.
Daniel 9:24-25
24
Seventy weeks are decreed on your people and on your holy city, to finish disobedience, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up vision and prophecy, and to anoint the most holy.
25
Know therefore and discern, that from the going forth of the commandment to restore and to build Jerusalem to the Anointed One, the prince, shall be seven weeks, and sixty-two weeks: it shall be built again, with street and moat, even in troubled times.
