'Left handed' in the Bible

But when the sons of Israel cried to the Lord, the Lord raised up a deliverer for them, Ehud the son of Gera, the Benjamite, a left-handed man. And the sons of Israel sent tribute by him to Eglon the king of Moab.

Out of all these people 700 choice men were left-handed; each one could sling a stone at a hair and not miss.
