Genesis 37

Joseph, Jacob's favorite son form Rachel is now seventeen. Joseph clearly loves him more than his brothers, and makes him a coat of many colors. Joseph being the youngest is a tattle-tale, often telling Jacob the misdeeds of his older brothers. They hate him.
Joseph then recants two dreams that clearly insinuates he will be bowed to, which adds peppery fuel to the accrued hatred. Joseph's brothers sell him into slavery and tells their father, Jacob that he passed away.
