This is the outcome of a justified war against an unlawful intruder or occupier in the land of Israel. Or in the case of Joshua’s conquest a holy war of judgement against the Canaanite tribes who had brought upon themselves the judgement of God through their moral actions.
Marrying a Captive Woman
deut 21 v 10 When thou goest forth to war against thine enemies, and the LORD thy God hath delivered them into thine hands, and thou hast taken them captive, 11 And seest among the captives a beautiful woman, and hast a desire unto her, that thou wouldest have her to thy wife; 12 Then thou shalt bring her home to thine house; and she shall shave her head, and pare her nails; And she shall put the raiment of her captivity from off her, and shall remain in thine house, and bewail her father and her mother a full month: and after that thou shalt go in unto her, and be her husband, and she shall be thy wife.
It depends on the circumstances of the conflict if the blood of her family was shed or not. During the conquests of the cleansing of the land if the people surrendered their lives were spared and they became subservient. If they refused to surrender the males were put to death. The people became slaves or paid tribute. She had the right to mourn whatever family she had for a month.
Forced marriage plus kidnapping.
If the daughters of Shiloh come out to dance in dances, then come ye out of the vineyards, and catch you every man his wife of the daughters of Shiloh, and go to the land of Benjamin.
Most marriages were arranged anyway in those days. We are not seeing kidnapping for ransom here but to make a happy marriage. There is a slight difference.
Slave Market in the OT.
And I will sell your sons and your daughters into the hand of the children of Judah, and they shall sell them to the Sabeans, to a people far off: for the LORD hath spoken it.
As recompense for a crime, like for like. See the context:
Joel 3 v 4 Yea, and what have ye to do with me, O Tyre, and Zidon, and all the coasts of Palestine? will ye render me a recompence? and if ye recompense me, swiftly and speedily will I return your recompence upon your own head; 5 Because ye have taken my silver and my gold, and have carried into your temples my goodly pleasant things:6 The children also of Judah and the children of Jerusalem have ye sold unto the Grecians, that ye might remove them far from their border. 7 Behold, I will raise them out of the place whither ye have sold them, and will return your recompence upon your own head: 8 And I will sell your sons and your daughters into the hand of the children of Judah, and they shall sell them to the Sabeans, to a people far off: for the LORD hath spoken it.
Slave Market in the Gospel.
But forasmuch as he had not to pay, his lord commanded him to be sold, and his wife, and children, and all that he had, and payment to be made.
Not a market because slaves have no debts because they have no possessions. A reduction to slavery because of the inability to pay off the debt. Jesus is recognizing the right of the creditor to take action for the debt to be repaid. It does not necessarily mean that chattel slavery is in view here.
And if a man sell his daughter to be a maidservant, she shall not go out as the menservants do.
Not really. Rather the selling of one’s labour to pay off a debt. The going out refers to the freedom from compulsion to serve the creditor.
