Deuteronomy 21:16 Meaning and Commentary

Deuteronomy 21:16

Then it shall be, when he maketh his sons to inherit that
which he hath
By a will in writing, or byword of mouth, or by a deed of gift, actually bestowing his goods upon them, and dividing among them what he is for the present possessed of; see ( Luke 15:12 ) ,

that he may not make the son of the beloved firstborn before the son
of the hated, [which is] indeed the firstborn;
that is, when such is the case, that the son of his wife he has the least value for is really his firstborn, he may not, through favour and affection to the wife he loves better, prefer her son, and declare him to be the firstborn, by devising to him or bestowing on him the double portion of his goods; for so to do would not be right, or agreeably to the will and law of God; for though previous to this law the birthright was given to Joseph, the eldest son of Rachel, the most beloved wife of Jacob, before Reuben who was the son of Leah, less beloved by him, and was in fact his firstborn; yet this was owing to the sin of Reuben, and by the appointment of God; see ( Genesis 49:3 Genesis 49:4 ) ( 1 Chronicles 5:2 1 Chronicles 5:3 ) .

16 then, when it comes time for him to pass his inheritance on to his sons, he may not give the inheritance due the firstborn to the son of the loved wife in place of the son of the unloved one, who is in fact the firstborn.

17 No, he must acknowledge as firstborn the son of the unloved wife by giving him a double portion of everything he owns, for he is the firstfruits of his manhood, and the right of the firstborn is his.

18 "If a man has a stubborn, rebellious son who will not obey what his father or mother says, and even after they discipline him he still refuses to pay attention to them;
