211 "If in the land that the Lord your God is giving you to possess someone is found slain, lying in the open country, and it is not known who killed him, 2 then your elders and your judges shall come out, and they shall measure the distance to the surrounding cities. 3 And the elders of the city that is nearest to the slain man shall take a heifer that has never been worked and that has not pulled in a yoke. 4 And the elders of that city shall bring the heifer down to a valley with running water, which is neither plowed nor sown, and shall break the heifer's neck there in the valley. 5 Then the priests, the sons of Levi, shall come forward, for the Lord your God has chosen them to minister to him and to bless in the name of the Lord, and by their word every dispute 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 and they shall testify, 'Our hands did not shed this blood, nor did our eyes see it shed. 8 Accept atonement, O Lord, for your people Israel, whom you have redeemed, and do not set the guilt of innocent blood in the midst of your people Israel, so that their blood guilt be atoned for.' 9 So you shall purge the guilt of innocent blood from your midst, 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 gives them into your hand and you take them captive, 11 and you see among the captives a beautiful woman, and you desire to take her to be your wife, 12 and you bring her home to your house, she shall shave her head and pare her nails. 13 And she shall take off the clothes in which she was captured and shall remain in your house and lament 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 But if you no longer delight in her, you shall let her go where she wants. But you shall not sell her for money, nor shall you treat her as a slave, since you have humiliated her.
15 "If a man has two wives, the one loved and the other unloved, and both the loved and the unloved have borne him children, and if the firstborn son belongs to the unloved,[1] 16 then on the day when he assigns his possessions as an inheritance to his sons, he may not treat the son of the loved as the firstborn in preference to the son of the unloved, who is the firstborn, 17 but he shall acknowledge the firstborn, the son of the unloved, by giving him a double portion of all that he has, for he is the firstfruits of his strength. The right of the firstborn is his.
Matthew Henry's Commentary on Deuteronomy 21:1-17
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.
