That this signifies communication, is evident from the signification of “eating,” as being to be communicated in respect to the things that are of good (n. 2187, 2343, 3168); and from the signification of “drinking,” as being to be communicated in respect to the things that are of truth (n. 3089, 3168).
Leviticus 22:4-7
4
"'Whoever of the seed of Aaron is a leper or has an issue; he shall not eat of the holy things, until he is clean. Whoever touches anything that is unclean by the dead, or a man whose seed goes from him;
5
or whoever touches any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatever uncleanness he has;
6
the person that touches any such shall be unclean until the evening, and shall not eat of the holy things, unless he bathe his body in water.
7
When the sun is down, he shall be clean; and afterward he shall eat of the holy things, because it is his bread.
