Arcana Coelestia #8058
8058. 'Seven days you shall eat unleavened bread' means purification from falsities. This is clear from the meaning of 'seven days' as that which implies something holy, dealt with in 395, 433, 716, 881, 5265, 5268, and as a complete state, 6508; and from the meaning of 'eating unleavened bread' as making truth one's own and as purification from falsity, for 'the unleavened' is good purified from falsity, and 'eating' making one's own, 3168, 3513, 3596, 3832, 4745. The reason why 'the unleavened' is good purified from falsity is that 'bread' means good and 'yeast' falsity.

3168. 'And they ate and drank' means making one's own the good and truth introduced in this way. This is clear from the meaning of 'eating' as being communicated and joined together, thus being made one's own, dealt with in 2187, 2343, and more specifically (since 'eating' has reference to bread and 'bread' means good, 276, 680, 2165, 2177, 2187) making good one's own; and from the meaning of 'drinking' as being communicated and joined together, thus being made one's own, dealt with in 3089, and more specifically (since 'drinking' has reference to wine and 'wine' means truth, 1071, 1798) making truth one's own. The situation is as stated above in 3167, namely that when truth is introduced into good in the rational, more so when it is joined to it, the good and truth of the spiritual man, that is, spiritual things, become made over to the natural as its own.
