So far as our examples go, some color might be given to the suggestion that adoption was always merely for the convenience of old people who wanted to be taken care of. But we know that children were adopted on other grounds. That they were children and not always grown-up men and women is clear from the above. This we may regard as adoption pure and simple. Other cases are a legal method of making provision for old age, or for other purposes for which an heir as legal representative was desirable. In the case of no legal heir, the property went back to the next of kin. (M395) That such a process did take place in Babylonia is made clear by the Code.(378) But few examples are known where a father takes into his family an additional child. The case, in which the son is not only adopted by parents who have a family living, but is ranked as their eldest son, deserves reproducing in full.(379) Ubar-Shamash, son of Sin-idinnam, from Sin-idinnam, his father, and Bititum, his mother, have Beltum-abi and Taram-ulmash taken to sonship, and let him be the son of Beltum-abi and Taram-ulmash. Ubar-Shamash shall be their eldest son. The day that Beltum-abi, his father, and Taram-ulmash, his mother, say to Ubar-Shamash, their son, “You are not our son,” he shall leave house and furniture. The day that Ubar-Shamash shall say to Beltum-abi, his father, or Taram-ulmash, his mother, “You are not my father or my mother,” one shall brand him, put fetters upon him, and sell him. Both parents of the adopted son were living. That the son is to be reckoned eldest implies that the adopting parents had other children. This is made clear in one case where the adoptive parents are expressly said to have five children.(380) In another case where a child is adopted a certain person is expressly said to be his brother.(381) (M396) The existing members of the family had a real interest in the proceeding. For, as inheriting with them, the addition of another son could not but affect their prospects. We may wonder what influenced them to consent. That they did consent is clear from the often-occurring covenant by which they bound themselves not to object. One explanation may be that they had grown up and left home and were anxious for the welfare of their parents, but could not arrange to look after them themselves. Hence for their parents’ sake they were willing to forego their share, or submit to a stranger taking precedence of them, or in some cases to give up all claim to the property in their parents’ possession in return for being relieved of the responsibility of looking after them. Of course, when the adopted son was only taken in as one, even the eldest, among several, he would only have a share at the parents’ death. But it even seems that the children might of their own motion adopt a brother to be son to their parents.(382)
