'Left handed' in the Bible

But when the people of Israel cried to the LORD, the LORD raised up for them a deliverer, Ehud, the son of Gera, the Benjaminite, a left-handed man. The people of Israel sent tribute by him to Eglon the king of Moab.

Among all these were seven hundred picked men who were left-handed; every one could sling a stone at a hair, and not miss.
