Deuteronomy 21:16

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.

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, 21:16 Lit against the face ofat the expense of the son of the 21:16 See note v 15unloved, who actually is the firstborn son.

16then it shall be in the day he wills what he has to his sons, he cannot make the son of the loved the firstborn before the son of the unloved, who is the firstborn.

16then on the day when he wills his possessions to his sons, he cannot treat the son of his loved wife as firstborn in place of the son of the unloved wife—the [actual] firstborn.

16when 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.

16Someday he’ll leave his property to his sons. When he does, he must not give the rights of the oldest son to the son of the wife he loves. He must give those rights to his oldest son. He must do it even though his oldest son is the son of the wife he doesn’t love.
