Vayikra 25:53-55

Orthodox Jewish Bible

⁵³ And as a sakhir hired shanah b’shanah shall he be with him; and the other shall not rule with rigor over him in thy sight.

⁵⁴ And if he be not redeemed in these shanim, then he shall be released in the Shnat HaYovel, both he, and his banim with him.

⁵⁵ For unto Me the Bnei Yisroel are avadim; they are My avadim whom I brought forth out of Eretz Mitzrayim: I am Hashem Eloheichem.
