What did rachel consern about when she saw leah giving birth?

 

I think that rachel was angry when she saw leah giving birth because rachel is the firstborn and back then the rule was the oldest has to get married first.Rachel was mad for no reason beacuse Leah was older. Also laban said he would give Rachel to Jacob if he worked for 7 years. Laban  Jacob worked for seven years and he got Leah instead of Rachel.
