Deuteronomy 21:16

16 and the father will part his chattel betwixt his sons, he shall not be able to make the son of the loved wife his first begotten son, and set him before the son of the hateful wife, (and the father will divide his possessions between his sons, he shall not be able to make the son of the loved wife his first-born son, and set him before the son of the hated wife,)

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 ) .

Deuteronomy 21:16 In-Context

14 But if afterward she sitteth not in thy soul, that is, (if she) pleaseth not thy will, thou shalt deliver her free, neither thou shalt be able to sell her for money, neither oppress by power, for thou madest her low. (But if afterward she sitteth not right with thy soul, that is, if she pleaseth not thy will, thou shalt set her free, and thou shalt not be able to sell her for money, nor oppress her by force, for thou hast made her low.)

15 If a man hath two wives, one loved, and another hateful, and he begetteth of her free children, and the son of the odious wife is the first begotten, (If a man hath two wives, one loved, and the other hated, and he begetteth children with them, and the son of the hated wife is the first-born,)

16 and the father will part his chattel betwixt his sons, he shall not be able to make the son of the loved wife his first begotten son, and set him before the son of the hateful wife, (and the father will divide his possessions between his sons, he shall not be able to make the son of the loved wife his first-born son, and set him before the son of the hated wife,)

17 but he shall know the son of the hateful wife to be his first begotten son, and he shall give to that son all things double of those things that he hath; for this son is the beginning of his free children, and the first engendered things be due to him. (but he shall acknowledge the son of the hated wife to be his first-born son, and he shall give double to that son of all the things that he hath; for this son is the first of his children, and the rights of the first-born son be due to him.)

18 If a man beget a son (who is a) rebel, and a froward (boy), that heareth not the behest of his father and mother, and he is chastised, and despiseth to obey to them, (If a man beget a son who is rebellious, and froward, who obeyeth not his father or his mother, and after that he is chastised, he still despiseth to obey them,)
