The Torah, “Leviticus” 25:47- 48: If a resident non Jew gains wealth with you, and your brother becomes destitute with him and is sold to a resident non Jew among you or to an idol of the family of a non Jew. After he is sold, he shall have redemption; one of his brothers shall redeem him.
A stranger is the external ego that in and of itself becomes a greater level in relation to the people of Israel (Galgalta ve Eynaim). This speaks about corrected states. So, if there is a stranger who settles with you and gets the upper hand, meaning that he becomes great and corrected, then your brother who is smaller than he in level, his sale to a stranger becomes his correction. You must sell him because entry under a higher level with a greater ego, called a stranger, is the correction.
However, after you have sold your brother to a stranger, you can redeem and buy him back, for he has already corrected himself by being sold, meaning he nullified himself to the stranger. When the redemption ransoms him, he returns to you together with that part of the stranger that he acquired at the time of the sale.
The only situation in which the sale is considered a sin is prostitution, meaning I am sold to another for the purpose of obtaining pleasure, not in order to adhere to him and do great work. So, from prostitution, we don’t take a tithe because the Partzuf itself is not sacred since it is not working with an intention to bestow. It has Aviut (thickness/coarseness), but there is no Masach (screen), the intention to bestow.
After he is sold, he shall have redemption; one of his brothers shall redeem him. Or his uncle or his cousin shall redeem him, or the closest [other] relative from his family shall redeem him; or, if he becomes able to afford it, he can be redeemed [on his own]. He shall calculate with his purchaser [the number of years] from the year of his being sold to him until the Jubilee year; then, the purchase price shall be [divided] by the number of years; as the days of a hired worker, he shall be with him. (Leviticus 25:48 – 25:50)
Redeeming the brother means paying with a Masach for a Masach, since someone who goes through correction is under the Masach of a greater Partzuf. He needs to wait (which means to pass through levels) until the year of the Jubilee (Bina) when everyone becomes free, and everything goes back to its true owner.
It is necessary to pay for that work that the master must carry out on the brother (on the uncorrected desire) until the Jubilee year (Bina), meaning that he does this work instead of the master, and then the brother can go free.
Suppose that I have 17 years until the Jubilee year (50 years). This means that I must pay for a Masach corresponding to these 17 years. I then take him from under the Masach of the master to my Masach. However, if I ransom him, meaning to free him, does he truly become free, since after all, my Masach has not been moved to anyone? The question can be asked, “What do we rely on to acquire a Masach here?”
This is the redemption, the ransom, that specifically happens in this order when, …one of his brothers shall redeem him. Or his uncle or his cousin shall redeem him, or the closest [other] relative from his family shall redeem him; or, if he becomes able to afford it, he can be redeemed [on his own]. This indicates that the correction has been done to the degree that the Masach has been reduced.
The ransom of captives, slaves, and various other people is a very great correction, a real act of charity and kindness. There is even a ransom of bodies that were murdered. This strengthens the spirit of the people, giving them faith that we will not leave anyone behind. This is just like when Moses upheld the condition of taking everyone out of Egypt without leaving even one under the Parsa (border). For, if we are one soul, then it is impossible to leave any fragment behind, because without it we never can attain the entire completion of correction.
