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.

84. Verses 2-3 And on the seventh day God finished His work which He had made, and rested on the seventh day from all His work which He had made. And God blessed the seventh day and made it holy, for on that day He rested from all His work which God had created when making it.
The celestial man is 'the seventh day'; and because throughout the six days it has been the Lord at work, that man is called 'His work'. In addition, because conflict at that point ceases, the Lord is said 'to rest from all His work'. It was for this reason that the seventh day was made holy and was called the Sabbath from a word for 'rest'; and it was in this manner that man was created, formed, and made, as may be seen plainly from the words themselves.
