Arcana Coelestia # 4845
4845. Till Shelah my son be grown up. That this signifies until the time, is evident from the signification of “growing up,” as being to be of this age, thus until the time; and from the representation of Shelah, the son, as being what is idolatrous, of which above (n. 4825, 4826), thus the Jewish religion, which with them was idolatrous (n. 4825) Hence by the words, “till Shelah my son be grown up,” is signified until the time that the Jewish religion can receive internal things, or the spiritual and celestial things of the representative church, which is Tamar (n. 4829, 4831, 4843).
Exodus 22:21-24
21
"You shall not wrong an alien, neither shall you oppress him, for you were aliens in the land of Egypt.
22
"You shall not take advantage of any widow or fatherless child.
23
If you take advantage of them at all, and they cry at all to me, I will surely hear their cry;
24
and my wrath will grow hot, and I will kill you with the sword; and your wives shall be widows, and your children fatherless.
