Devarim 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 ) .

15 If an ish have two nashim, one beloved, and another hated, and they have born him banim, both the beloved and the hated; and if the bechor be hers that was hated;

16 Then it shall be, on the yom when he wills his possessions to his banim, that he may not make the ben of the beloved bechor before the ben of the hated, which is indeed the bechor;

17 But he shall acknowledge the ben of the hated for the bechor, by giving him a double portion of all that he hath; for he is the beginning of his strength; the mishpat habechorah (right of the firstborn) is his.

18 If an ish have a stubborn and rebellious ben, which will not obey the voice of his av, or the voice of his em, and that, when they have chastened him, will not give heed unto them;
