Deuteronomy 21:17

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 make merchandise of her, because thou hast humbled her.

15 If a man have two wives, one beloved, and another hated, and they have born him children, [both] the beloved and the hated; and [if] the firstborn son be hers that was hated:

16 Then it shall be, when he maketh his sons to inherit [that] which he hath, [that] he may not make the son of the beloved firstborn before the son of the hated, [which is indeed] the firstborn:

17 But he shall acknowledge the son of the hated [for] the firstborn, by giving him a double portion of all that he hath: for he [is] the beginning of his strength; the right of the firstborn [is] his.

18 If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and [that], when they have chastened him, will not hearken unto them:

19 Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place;

20 And they shall say unto the elders of his city, This our son [is] stubborn and rebellious, he will not obey our voice; [he is] a glutton, and a drunkard.
