Танах к Шмот 21:2

כִּ֤י תִקְנֶה֙ עֶ֣בֶד עִבְרִ֔י שֵׁ֥שׁ שָׁנִ֖ים יַעֲבֹ֑ד וּבַ֨שְּׁבִעִ֔ת יֵצֵ֥א לַֽחָפְשִׁ֖י חִנָּֽם׃

Если ты купишь еврейского слугу, шесть лет он будет служить; и в седьмом он выйдет на свободу бесплатно.

Deuteronomy

If your brother—Jew or Jewess—is sold to you and he serves you six years; then in the seventh year you are to send him free from you.

Leviticus

If a man lies with a woman in a conjugal manner, and she is a maid-servant designated for a [specific] man and she has certainly not been redeemed, or her freedom was not given to her; there shall be an investigation they shall not be put to death, for her freedom was not given to her.

Exodus

If the sun shone on him, there is liability for his blood. He must make full restitution. If he does not have [the means to do so], he shall be sold [as a slave to pay] for his theft.
