'Seventeen' in the Bible

These are the records of the generations of Jacob.Joseph, 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.

Jacob lived in the land of Egypt seventeen years; so the length of Jacob’s life was one hundred and forty-seven years.
