'Twelve' in the Bible

And when he was come into his house, he took a knife, and laid hold on his concubine, and divided her, limb by limb, into twelve pieces, and sent her throughout all the borders of Israel.

And the congregation sent thither twelve thousand men of the valiantest, and commanded them, saying, Go and smite the inhabitants of Jabesh-gilead with the edge of the sword, with the women and the little ones.
