Genesis 37:2-4

These are the records of the generations of Jacob. J oseph, when seventeen years of age, was pasturing the flock with his brothers while he was still a youth, along with the sons of Bilhah and the sons of Zilpah, his father’s wives. And Joseph brought back a bad report about them to their father. Now Israel loved Joseph more than all his sons, because he was the son of his old age; and he made him a varicolored tunic. His brothers saw that their father loved him more than all his brothers; and so they hated him and could not speak to him on friendly terms.
