Arcana Coelestia #2188
2188. Verse 9. And they said unto him, Where is Sarah thy wife? And he said, Behold, in the tent. “They said to him, Where is Sarah thy wife?” signifies rational truth, which did not then appear because it was in rational good; “and he said, Behold, in the tent,” signifies that it was in what is holy.
Leviticus 7:19-21
19
"'The flesh that touches any unclean thing shall not be eaten. It shall be burned with fire. As for the flesh, everyone who is clean may eat it;
20
but the soul who eats of the flesh of the sacrifice of peace offerings, that belongs to Yahweh, having his uncleanness on him, that soul shall be cut off from his people.
21
When anyone touches any unclean thing, the uncleanness of man, or an unclean animal, or any unclean abomination, and eats some of the flesh of the sacrifice of peace offerings, which belong to Yahweh, that soul shall be cut off from his people.'"
