Verse 11

In the fifth year of Abram's dwelling in the land of Canaan the people of Sodom and Gomorrah and all the cities of the plain revolted from the power of Chedorlaomer, king of Elam; for all the kings of the cities of the plain had served Chedorlaomer for twelve years, and given him a yearly tax, but in those days in the thirteenth year, they rebelled against him.
