'Seventeen' in the Bible

These [are] the generations of Jacob. Joseph, [being] seventeen years old, was shepherding the flock with his brothers. Now he [was] a helper with the sons of Bilhah and the sons of Zilpah, the wives of his father. And Joseph brought a bad report of them to his father.

And Jacob lived in the land of Egypt seventeen years. And the days of Jacob, the years of his life, were one hundred and forty-seven years.
