then on the day he distributes his inheritance to his sons, he may not elevate the son of the favored wife to firstborn status at the expense of the son of the unloved wife, who is the true firstborn.
then on the day he assigns inheritance to his sons, he may not make the son of the loved wife the firstborn over the son of the unloved, who is the true firstborn.
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:
when that man assigns his inheritance to his sons he must not appoint the son of the beloved wife as the firstborn over the son of the unloved wife.
