© Charles Chandler Tanakh commentary Genesis 37 Genesis 39 Genesis 40 This starts with Joseph being 17 years old, which would have been 1301 bce if he had been born in 1318 bce (i.e., 6 years old on the return from Mitanni in 1312 bce). This is consistent with it coming after the Israelite conquest, and Jacob's subsequent move to Hebron.
