Arcana Coelestia #4845
4845. 'Until Shelah my son is grown up' means until the time. This is clear from the meaning of 'growing up' as being of that age, and so as until the time; and from the representation of 'Shelah my son' as idolatry, dealt with above in 4825, 4826, and so as the Jewish religion which, compared with others, was idolatrous, 4825. Consequently the words 'until my son Shelah is grown up' mean until the time that the Jewish religion was able to accept internal things willingly, that is, the spiritual and celestial things of the representative Church, meant by 'Tamar', 4829, 4831, 4843.
Leviticus 22:12-13
12
If a priest's daughter is married to an outsider, she shall not eat of the heave offering of the holy things.
13
But if a priest's daughter is a widow, or divorced, and has no child, and has returned to her father's house, as in her youth, she may eat of her father's bread: but no stranger shall eat any of it.
