That is a clear violation of:
Do unto others, as you would have them do unto you.
Or men, treat females, just as you would wish females to treat you.
LOL!! I*t is a fact that Jewish tradition was a patriarchal society---period. It Doesn't matter what you think about it, it is fact. The birthright never included women, only the firstborn male---one reason for that being that the Messiah was expected to be born at any time. The other reason being that:
Gen 3:16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.
It wasn't until this that women had any inheritance at all:
Num 27:1 Then came the daughters of Zelophehad, the son of Hepher, the son of Gilead, the son of Machir, the son of Manasseh, of the families of Manasseh the son of Joseph: and these are the names of his daughters; Mahlah, Noah, and Hoglah, and Milcah, and Tirzah.
Num 27:2 And they stood before Moses, and before Eleazar the priest, and before the princes and all the congregation, by the door of the tabernacle of the congregation, saying,
Num 27:3 Our father died in the wilderness, and he was not in the company of them that gathered themselves together against the LORD in the company of Korah; but died in his own sin, and had no sons.
Num 27:4 Why should the name of our father be done away from among his family, because he hath no son? Give unto us therefore a possession among the brethren of our father.
Num 27:5 And Moses brought their cause before the LORD.
Num 27:6 And the LORD spake unto Moses, saying,
Num 27:7 The daughters of Zelophehad speak right: thou shalt surely give them a possession of an inheritance among their father's brethren; and thou shalt cause the inheritance of their father to pass unto them.
Num 27:8 And thou shalt speak unto the children of Israel, saying, If a man die, and have no son, then ye shall cause his inheritance to pass unto his daughter.
Num 27:9 And if he have no daughter, then ye shall give his inheritance unto his brethren.
Num 27:10 And if he have no brethren, then ye shall give his inheritance unto his father's brethren.
Num 27:11 And if his father have no brethren, then ye shall give his inheritance unto his kinsman that is next to him of his family, and he shall possess it: and it shall be unto the children of Israel a statute of judgment, as the LORD commanded Moses.
The idea of there being no male or female before God, was not until NT.
