'Left handed' in the Bible

But when the sons of Israel cried to LORD, LORD raised up for them a savior, 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.

Among all this people there were seven hundred chosen men left-handed. Every one could sling stones at a hair-breadth, and not miss.
