Deuteronomy 21:14-17

14And it shall beH1961, if thou have no delightH2654 in her, then thou shalt let her goH7971 whither she will; but thou shalt not sellH4376 her at all for moneyH3701, thou shalt not deal with her as a slave, because thou hast humbled her.

15If a manH376 have twoH8147 wivesH802, the oneH259 beloved, and the other hatedH8130, and they have borneH3205 him children, both the beloved and the hatedH8130; and if the first-born sonH1121 beH1961 hers that wasH1961 hatedH8130; 16then it shall beH1961, in the dayH3117 that he causeth his sonsH1121 to inheritH5157 that which he hath, that he may not make the sonH1121 of the beloved the first-born before the sonH1121 of the hatedH8130, who is the first-born: 17but he shall acknowledgeH5234 the first-born, the sonH1121 of the hatedH8130, by givingH5414 him a double portion of all that he hath; for he is the beginning of his strengthH202; the rightH4941 of the first-born is his.
