Hi Linn
Interesting question...
As far as I understand, a concubine was a slave-wife. She [u][i]was[/i][/u] a proper wife, but didn't have the same status as the free woman. Paul of course allegorises this in Galatians.
You will know of course the importance in that culture of having sons. From the Biblical accounts, it seems it was the custom for a girl to be given a slave (or maybe more than one?) as a maid when she married. The maid would act as "insurance" so that (especially if the wife failed to have children) her husband could marry the maid as well.
From the accounts of Abraham and Sarah, and of Jacob with Rachel and Leah, it seems that the husband had no rights to these slave girls, they belonged to the wife. The wife alone had the right to [i][u]give[/u][/i] the girl to her husband as a wife, the husband couldn't just take her.
Any children of this union would legally be the chief wife's, not the concubine's. And presumably, if the chief wife had a son afterwards (as with Sarah) that son, not the son of the slave, would inherit his father's property.
However, when Abraham sent Ishmael and Hagar away he was in effect divorcing Hagar and disowning Ishmael. When he married again after Sarah's death he also sent the sons of these wives away, but with an inheritance (Genesis 25). Ishmael and his mother, on the other hand doesn't seem to have been given anything except a few provisions for the journey.
If the chief wife (or wives) had no sons the son of the slave would inherit instead. Or even the senior slave, whether his master's son or not, if there was no-one else to inherit.
Genesis 15[color=990000]2 But Abram said, “O Lord GOD, what wilt thou give me, for I continue childless, and the heir of my house is Eliezer of Damascus?” 3 And Abram said, “Behold, thou hast given me no offspring; and a slave born in my house will be my heir.”[/color]
I think it was probably very unusual that Abraham hadn't taken a concubine before, as he and Sarah had been married for many years without children. To me it says a lot about Abraham's great love for her.
In the time of Moses, God gave strict laws governing treatment of female slaves who were taken as concubines. I was especially struck by the parts underlined:
Exodus 21:
[color=990000] 7 “When a man sells his daughter as a slave, she shall not go out as the male slaves do. 8 If she does not please her master, who has designated her for himself, then he shall let her be redeemed; he shall have no right to sell her to a foreign people, since he has dealt faithlessly with her. 9 If he designates her for his son, he shall deal with her as with a daughter. 10 If he takes another wife to himself, [u]he shall not diminish her food, her clothing, or her marital rights[/u]. 11 And if he does not do these three things for her, she shall go out for nothing, without payment of money.[/color]
Even if he takes another wife who is not a slave he must not neglect his concubine in any way!
Deuteronomy 21
[color=990000]10 “When you go forth to war against your enemies, and the Lord your God gives them into your hands, and you take them captive, 11 and see among the captives a beautiful woman, and you have desire for her and would take her for yourself as wife, 12 then you shall bring her home to your house, and she shall shave her head and pare her nails. 13 And she shall put off her captive’s garb, and shall remain in your house [u]and bewail her father and her mother a full month[/u]; after that you may go in to her, and be her husband, and she shall be your wife. 14 Then, if you have no delight in her, you shall let her go where she will; but [u]you shall not sell her for money, you shall not treat her as a slave, since you have humiliated her[/u].[/color]
Slavery was a fact of life, yet a girl was allowed to mourn and had her rights, including the right to her freedom if she wasn't treated properly. Most slaves in other cultures of those days had no rights.
