“Twelue yeeres they serued Chedorlaomer, and in the thirteenth yeere they rebelled.”
1611 King James Version (KJV)
14:4 Twelve years they served him - The Sodomites were the posterity of Canaan, whom Noah had pronounced a servant to Shem, from whom Elam descended. Thus soon did that prophecy begin to be fulfilled. In the thirteenth year, beginning to be weary of their subjection, they rebelled - Denied their tribute, and attempted to shake off the yoke.
