Contradiction with Leviticus 25:46
Leviticus 25:46 discusses passing inheritance to one's children as possessions, which can be seen as contradictory because Numbers 27:9 involves inheritance laws when there are no sons.
Leviticus 25:46: And ye shall take them as an inheritance for your children after you, to inherit [them for] a possession; they shall be your bondmen for ever: but over your brethren the children of Israel, ye shall not rule one over another with rigour. [they...: Heb. ye shall serve yourselves with them]
Contradiction with Deuteronomy 21:15-17
Deuteronomy 21:15-17 outlines laws of inheritance for firstborn sons, implying male preference, which contrasts with Numbers 27:9's inclusion of daughters when there are no sons.
Deuteronomy 21:15-17: If a man have two wives, one beloved, and another hated, and they have born him children, [both] the beloved and the hated; and [if] the firstborn son be hers that was hated:
Contradiction with Numbers 36:7
Numbers 36:7 emphasizes inheritance staying within a tribe, adding complexity to Numbers 27:9's rules about passing inheritance to daughters if there are no sons.
Numbers 36:7: So shall not the inheritance of the children of Israel remove from tribe to tribe: for every one of the children of Israel shall keep himself to the inheritance of the tribe of his fathers. [keep...: Heb. cleave to the, etc]
