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.
This verse says that Jacob had children, including Joseph who was 17 years old. He took care of sheep with his siblings. Joseph was also with the children of Bilhah and Zilpah, who were Jacob's other wives. Joseph told his dad bad things about his brothers.
