레위기 25:13의 주석

תשבו איש אל אחזתו YE SHALL RETURN EVERY MAN UNTO IHS POSSESSION — But has it not already been stated: (v. 10) “and ye shall return every man unto his possession”? But this is repeated in order to include in this law also the case of one who sold his field and his son came forward and redeemed it, — that it also is to be returned to the father in the Jubilee (Sifra, Behar, Chapter 3 6).

תשובו איש אל אחוזתו; it is permitted for the owners to take possession of it as their ancestral heritage, and to use it to build houses thereon, construct pens for the flocks, etc., as proof that it is again theirs.

It returns to his father in the Jjubilee. I.e., do not say that since his son will inherit him [anyway], the field should not return to his father in the jubileeJubilee.
