Genesis 37:2-5

These are the generations of Jacob. Joseph, being seventeen years old, was feeding the flock with his brethren; and the lad was with the sons of Bilhah, and with the sons of Zilpah, his father's wives: and Joseph brought unto his father their evil report. Now Israel loved Joseph more than all his children, because he was the son of his old age: and he made him a coat of many colours. And when his brethren saw that their father loved him more than all his brethren, they hated him, and could not speak peaceably unto him. And Joseph dreamed a dream, and he told it his brethren: and they hated him yet the more.
