Deuteronomio 14:1 Cabala: Zohar & Or Neerav

Rabbi Abba went to the field of Kanya (other versions: to do business) to the cave in Lod. With him were Rabbi Yosi and Rabbi Hyiah. Rabbi Yosi said: it is written "a woman of valor is a crown to her husband etc" (Proverbs 12:4). A woman of valor - this is the congregation of Israel. And when their very essence is rotten due to evil. They, (other versions: the religions of the other), the peoples, are strange service, that cannot be withstood by the Holy One of Blessing in the world, as it is written 'and I was angry [akutz] at them' (Lev. 20:21) - just like these thorns and lions that distress human beings, and they can't stand them. Rabbi Abba said: This is the obvious - 'woman of valor' is the congregation of Israel, since she is the mistress of many valorous men and many seeders that are found in the world. 'A crown to her husband' - just as you say, a crown of beauty [tif'eret] and all is one. [this is a wrong version: the 'woman of valor' is the congregation of Israel, that from the union of the king many men of valor, many seeders, many righteous people [appear] in the world, and all of them are called 'children of the Holy One of Blessing and of the Congregation of Israel' as it is written "you are children to Ad-nai your God" (Deut. 14:1).] Until they had walked, Rabbi Abba said: all is one, let us say a word about the congregation of Israel.

[The master of Kabbalah] also possesses a third advantage which is entwined in the two preceding ones. That is, one who serves [God] according to the plain meaning [of the Torah] and is drawn after it alone is classified according to the esoteric significance of the term “servants,” as it is written, For it is to Me that the children of Israel are servants; they are My servants (Lev. 25:55). He who occupies himself with Kabbalah and serves [God] according to the way of Kabbalah in the recondite meaning of the “intention” of the commandments is called “son.” Thus [Scripture] states, You are sons to the Lord your God (Deut. 14:1). There are many similar [verses], such as My firstborn son is Israel (Exod. 4:22). These praises are elaborated upon in the Tikkunim, the Ra’aya Mehemna, and countless times in the pikkudin.

And in this sense "whether as children or servants". If as children, that it is written regarding them "you are children to Ad-nai your God" (Deut. 14:1). If as servants "since the children of Israel are My servants" (Lev. 25:55). And not the rest of the nations. But those who are obligated and do not deal with Torah and mitzvot, and do not have the yoke of Torah and tefilin and the rest of the commandments, they are servants of the nations of the world, and are made slaves to them. As "we were slaves to Pharaoh in Egypt" (Deuteronomy 6:21).
