Numbers 27:1

Women in Israel had not, up to the present time, enjoyed any distinct right of inheritance. Yet a father, whether sons had been born to him or not, had the power, either before or at his death, to cause part of his estate to pass to a daughter; in which case her husband married into her family rather than she into his, and the children were regarded as of the family from which the estate had come. Thus, Machir, ancestor of Zelophehad, although he had a son Gilead, left also, as is probable, an inheritance to his daughter, the wife of Hezron of the tribe of Judah, by reason of which their descendants, among whom was Jair, were reckoned as belonging to the tribe of Manasseh (Numbers 32:41; 1 Chronicles 2:21 ff).
