Arcana Coelestia #852
852. That the “seventh month” signifies what is holy, is abundantly evident from what has been shown before (n. 84-87, 395, 716). This holiness corresponds to what was said with reference to the celestial man (Genesis 2:3): that the seventh day was sanctified, because God rested therein.
Leviticus 14:6-7
6
As for the living bird, he shall take it, and the cedar wood, and the scarlet, and the hyssop, and shall dip them and the living bird in the blood of the bird that was killed over the running water.
7
He shall sprinkle on him who is to be cleansed from the leprosy seven times, and shall pronounce him clean, and shall let the living bird go into the open field.
