There are some verses relating to women that I don't understand. Please clear them up for me, thanks!
I especially don't understand the next one, why are woman unpure longer if she gives birth to a girl than to a boy?:
A question for this next verse, why are the women worth less than the men?
Exodus:21:7-8
If a man sells his daughter as a servant, she is not to go free as menservants do. If she does not please the master who has selected her for himself, he must let her be redeemed. He has no right to sell her to foreigners, because he has broken faith with her.

Leviticus 12:1-8
The LORD said to Moses, "Say to the Israelites: 'A woman who becomes pregnant and gives birth to a son will be ceremonially unclean for seven days, just as she is unclean during her monthly period. On the eighth day the boy is to be circumcised. Then the woman must wait thirty-three days to be purified from her bleeding. She must not touch anything sacred or go to the sanctuary until the days of her purification are over. If she gives birth to a daughter, for two weeks the woman will be unclean, as during her period. Then she must wait sixty-six days to be purified from her bleeding.
" 'When the days of her purification for a son or daughter are over, she is to bring to the priest at the entrance to the Tent of Meeting a year-old lamb for a burnt offering and a young pigeon or a dove for a sin offering. He shall offer them before the LORD to make atonement for her, and then she will be ceremonially clean from her flow of blood.
" 'These are the regulations for the woman who gives birth to a boy or a girl. If she cannot afford a lamb, she is to bring two doves or two young pigeons, one for a burnt offering and the other for a sin offering. In this way the priest will make atonement for her, and she will be clean.' "
Leviticus 15: 19-30, 33
" 'When a woman has her regular flow of blood, the impurity of her monthly period will last seven days, and anyone who touches her will be unclean till evening.
" 'Anything she lies on during her period will be unclean, and anything she sits on will be unclean. Whoever touches her bed must wash his clothes and bathe with water, and he will be unclean till evening. Whoever touches anything she sits on must wash his clothes and bathe with water, and he will be unclean till evening. Whether it is the bed or anything she was sitting on, when anyone touches it, he will be unclean till evening.
" 'If a man lies with her and her monthly flow touches him, he will be unclean for seven days; any bed he lies on will be unclean.
" 'When a woman has a discharge of blood for many days at a time other than her monthly period or has a discharge that continues beyond her period, she will be unclean as long as she has the discharge, just as in the days of her period. Any bed she lies on while her discharge continues will be unclean, as is her bed during her monthly period, and anything she sits on will be unclean, as during her period. Whoever touches them will be unclean; he must wash his clothes and bathe with water, and he will be unclean till evening. 'When she is cleansed from her discharge, she must count off seven days, and after that she will be ceremonially clean. On the eighth day she must take two doves or two young pigeons and bring them to the priest at the entrance to the Tent of Meeting. The priest is to sacrifice one for a sin offering and the other for a burnt offering. In this way he will make atonement for her before the LORD for the uncleanness of her discharge.
for a woman in her monthly period, for a man or a woman with a discharge, and for a man who lies with a woman who is ceremonially unclean.

Leviticus 27:1-7
The LORD said to Moses, "Speak to the Israelites and say to them: 'If anyone makes a special vow to dedicate persons to the LORD by giving equivalent values, 3 set the value of a male between the ages of twenty and sixty at fifty shekels of silver, according to the sanctuary shekel ; and if it is a female, set her value at thirty shekels. If it is a person between the ages of five and twenty, set the value of a male at twenty shekels and of a female at ten shekels. If it is a person between one month and five years, set the value of a male at five shekels of silver and that of a female at three shekels of silver. If it is a person sixty years old or more, set the value of a male at fifteen shekels and of a female at ten shekels.
