211 "If anyone is found slain, lying in the field in the land which the Lord your God is giving you to possess, and it is not known who killed him, 2 then your elders and your judges shall go out and measure the distance from the slain man to the surrounding cities. 3 And it shall be that the elders of the city nearest to the slain man will take a heifer which has not been worked and which has not pulled with a yoke. 4 The elders of that city shall bring the heifer down to a valley with flowing water, which is neither plowed nor sown, and they shall break the heifer's neck there in the valley. 5 Then the priests, the sons of Levi, shall come near, for the Lord your God has chosen them to minister to Him and to bless in the name of the Lord; by their word every controversy and every assault shall be settled. 6 And all the elders of that city nearest to the slain man shall wash their hands over the heifer whose neck was broken in the valley. 7 Then they shall answer and say, 'Our hands have not shed this blood, nor have our eyes seen it. 8 Provide atonement, O Lord, for Your people Israel, whom You have redeemed, and do not lay innocent blood to the charge of Your people Israel.' And atonement shall be provided on their behalf for the blood. 9 So you shall put away the guilt of innocent blood from among you when you do what is right in the sight of the Lord.
10 "When you go out to war against your enemies, and the Lord your God delivers them into your hand, and you take them captive, 11 and you see among the captives a beautiful woman, and desire her and would take her for your wife, 12 then you shall bring her home to your house, and she shall shave her head and trim her nails. 13 She shall put off the clothes of her captivity, remain in your house, and mourn her father and her mother a full month; after that you may go in to her and be her husband, and she shall be your wife. 14 And it shall be, if you have no delight in her, then you shall set her free, but you certainly shall not sell her for money; you shall not treat her brutally, because you have humbled her.
15 "If a man has two wives, one loved and the other unloved, and they have borne him children, both the loved and the unloved, and if the firstborn son is of her who is unloved, 16 then it shall be, on the day he bequeaths his possessions to his sons, that he must not bestow firstborn status on the son of the loved wife in preference to the son of the unloved, the true firstborn. 17 But he shall acknowledge the son of the unloved wife as the firstborn by giving him a double portion of all that he has, for he is the beginning of his strength; the right of the firstborn is his.

Commentary on Deuteronomy 21:1-9
(Read Deuteronomy 21:1-9)
If a murderer could not be found out, great solemnity is provided for putting away the guilt from the land, as an expression of dread and detesting of that sin. The providence of God has often wonderfully brought to light these hidden works of darkness, and the sin of the guilty has often strangely found them out. The dread of murder should be deeply impressed upon every heart, and all should join in detecting and punishing those who are guilty. The elders were to profess that they had not been any way aiding or abetting the sin. The priests were to pray to God for the country and nation, that God would be merciful. We must empty that measure by our prayers, which others are filling by their sins. All would be taught by this solemnity, to use the utmost care and diligence to prevent, discover, and punish murder. We may all learn from hence to take heed of partaking in other men's sins. And we have fellowship with the unfruitful works of darkness, if we do not reprove them.
Commentary on Deuteronomy 21:10-14
(Read Deuteronomy 21:10-14)
By this law a soldier was allowed to marry his captive, if he pleased. This might take place upon some occasions; but the law does not show any approval of it. It also intimates how binding the laws of justice and honour are in marriage; which is a sacred engagement.
Commentary on Deuteronomy 21:15-17
(Read Deuteronomy 21:15-17)
This law restrains men from disinheriting their eldest sons without just cause. The principle in this case as to children, is still binding to parents; they must give children their right without partiality.
