The heirs of property in the Old Testament were normally the sons and, chief among these, the firstborn.
(1) -17 provides that the firstborn shall inherit a “double portion,†whence it would appear that all the other sons shared equally. (It should be noted that in this law the firstborn is the eldest son of the father, not of the mother as in .) Uncertain, however, is what -17 means by “wife,†and the practice must have varied. In the son of the handmaid was not to be heir with Isaac, but in -13 the sons of Bilhah and Zilpah are reckoned as legitimate children of Jacob. See MARRIAGE. Nor is it clear that -17 forbids setting aside the eldest son because of his own sin - compare the case of Reuben (, ; ), although the son of a regular wife (). The very existence of -17, moreover, shows that in spite of the absence of formal wills, a man could control to some extent the disposition of his property after his death and that the right of the firstborn could be set aside by the father (). That the royal dignity went by primogeniture is asserted only (in a particular case) in , and both David (-13) and Rehoboam (-23) chose younger sons as their successors. A single payment in the father's lifetime could be given in lieu of heritage (; ), and it was possible for two brothers to make a bargain as to the disposition of the property after the father's death (-34).
(2) When there were sons alive, the daughters had no right of inheritance, and married daughters had no such right in any case. ( describes an altogether exceptional procedure.) Probably unmarried daughters passed under the charge of the firstborn, as the new head of the family, and he took the responsibility of finding them husbands. -11; -12 treat of the case where there were no sons - the daughters inherited the estate, but they could marry only within the tribe, lest the tribal possessions be confused. This right of the daughters, however, is definitely stated to be a new thing, and in earlier times the property probably passed to the nearest male relatives, to whom it went in later times if there were no daughters. In extreme cases, where no other heirs could be found, the property went to the slaves (; , noting that the meaning of the latter verse is uncertain), but this could have happened only at the rarest intervals. A curious instance is that of , , where property is preserved in the family by marrying the daughter to an Egyptian slave belonging to the father; perhaps some adoption-idea underlies this.
(3) The wife had no claim on the inheritance, though the disposition made of her dowry is not explained, and it may have been returned to her. If she was childless she resorted to the Levirate marriage (-10). If this was impracticable or was without issue she returned to her own family and might marry another husband (; ; ). The inferior wives (concubines) were part of the estate and went to the heir; indeed, possession of the father's concubines was proof of possession of his dignities (, ; -25). At least, such was the custom in the time of David and Solomon, but at a later period nothing is heard of the practice.
(4) The disposition of land is a very obscure question. states explicitly that each heir had a share, but the continual splittin up of an estate through successive generations would have produced an impossible state of affairs. Possibly the land went to the eldest born as part of his portion, possibly in some cases it was held in common by the members of the family, possibly some member bought the shares of the others, possibly the practice differed at different times. But our ignorance of the facts is complete.
