'Twelve' in the Bible

And all the days of Seth were nine hundred and twelve years, and he died.

Twelve years they had served Kedorlaomer, but in the thirteenth year they rebelled.

And [as for] Ishmael, I have heard you. Behold, I will bless him and I will make him fruitful, and I will multiply him {exceedingly}. He shall father twelve princes, and I will make him a great nation.

Then they said, "We, your servants, [are] twelve brothers, the sons of one man in the land of Canaan, but behold, the youngest [is] with our father today, and one is no more."

We [are] twelve brothers, the sons of our father. One is no more and the youngest [is] with our father now in the land of Canaan.'

All these [are] the twelve tribes of Israel, and this [is] what their father said to them when he blessed them, each according to their blessing.
