Deuteronomy 21:14-16
New American Standard Bible
15If a man has two wives, the one loved and the other unloved, and both the loved and the unloved have borne him sons, and the firstborn son belongs to the unloved,
16then it shall be on the day that he wills what he owns as an inheritance to his sons, he is not allowed to treat the son of the loved wife as the firstborn, at the expense of the son of the unloved, who actually is the firstborn son.
King James Version
15If 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:
16Then 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:
Christian Standard Bible
15"If a man has two wives, one loved and the other neglected, and both the loved and the neglected bear him sons, and if the neglected wife has the firstborn son,
16when that man gives what he has to his sons as an inheritance, he is not to show favoritism to the son of the loved wife as his firstborn over the firstborn of the neglected wife.
New Living Translation
15Suppose a man has two wives, but he loves one and not the other, and both have given him sons. And suppose the firstborn son is the son of the wife he does not love.
16When the man divides his inheritance, he may not give the larger inheritance to his younger son, the son of the wife he loves, as if he were the firstborn son.
English Standard Version
15“If a man has two wives, the one loved and the other unloved, and both the loved and the unloved have borne him children, and if the firstborn son belongs to the unloved,
16then on the day when he assigns his possessions as an inheritance to his sons, he may not treat the son of the loved as the firstborn in preference to the son of the unloved, who is the firstborn,
New International Version
15If a man has two wives, and he loves one but not the other, and both bear him sons but the firstborn is the son of the wife he does not love,
16when he wills his property to his sons, he must not give the rights of the firstborn to the son of the wife he loves in preference to his actual firstborn, the son of the wife he does not love.
New King James Version
15“If a man has two wives, one loved and the other unloved, and they have borne him children, both the loved and the unloved, and if the firstborn son is of her who is unloved,
16then it shall be, on the day he bequeaths his possessions to his sons, that he must not bestow firstborn status on the son of the loved wife in preference to the son of the unloved, the true firstborn.
