Deuteronomy 21:16 ASV

¹⁴  And it shall be, if thou have no delight in her, then thou shalt let her go whither she will; but thou shalt not sell her at all for money, thou shalt not deal with her as a slave, because thou hast humbled her.

¹⁵  If a man have two wives, the one beloved, and the other hated, and they have borne him children, both the beloved and the hated; and if the first-born son be hers that was hated;

¹⁶  then it shall be, in the day that he causeth his sons to inherit that which he hath, that he may not make the son of the beloved the first-born before the son of the hated, who is the first-born:

¹⁷  but he shall acknowledge the first-born, the son of the hated, by giving him a double portion of all that he hath; for he is the beginning of his strength; the right of the first-born is his.

¹⁸  If a man have a stubborn and rebellious son, that will not obey the voice of his father, or the voice of his mother, and, though they chasten him, will not hearken unto them;
