“אִם-רָעָה בְּעֵינֵי אֲדֹנֶיהָ, אֲשֶׁר-לא (לוֹ) יְעָדָהּ–וְהֶפְדָּהּ: לְעַם נָכְרִי לֹא-יִמְשֹׁל לְמָכְרָהּ, בְּבִגְדוֹ-בָהּ”
“If she does not please her master, who has designated her for himself, then he shall let her be redeemed. He shall have no right to sell her to a foreign people, since he has broken faith with her.”
Some souls may reincarnate in a body of a different nation. God controls all the souls even if the other nations have separate ministers. (70 nations of the world have individual system of governance with a minister. The Israelites have direct connection to YHVH.)
Exodus 20:4 (From the ten Commandments)
“פֹּקֵד עֲוֹן אָבֹת עַל-בָּנִים עַל-שִׁלֵּשִׁים וְעַל-רִבֵּעִים, לְשֹׂנְאָי”
“ visiting the iniquity of the fathers on the children, on the third and the fourth generations of those who hate Me,”
The Holy Ari explains that ‘father’ is the aspect of first incarnation, the ‘son’ is the second and so on. After the fourth incarnation in the same line the soul may take a different path, including incarnation in an environment that is far from its original roots.
“וְעֹשֶׂה חֶסֶד, לַאֲלָפִים–לְאֹהֲבַי, וּלְשֹׁמְרֵי מִצְוֹתָי”
“but showing faithful love to a thousand generations of those who love Me and keep My commands. ”
The Holy Ari continues and reveal to us that God has mercy on the souls that wish to come back to the path and follow the Torah. God lets them reincarnate up to 2000 times with opportunities to purify their souls.
The process of reincarnation is not easy. The soul suffers greatly on each ‘travel’ to the material body. It is like being sent to a prison for a lifetime of hard labor.
