'Seventeen' in the Bible

These are the generations of Jacob. Joseph, being seventeen years old, fed the flock with his brethren; and he was doing service with the sons of Bilhah, and with the sons of Zilpah, his father's wives. And Joseph brought to his father an evil report of them.

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