'Left handed' in the Bible

Then the Israelites cried out to the Lord, and He raised up Ehud son of Gera, a left-handed Benjaminite, as a deliverer for them. The Israelites sent him to Eglon king of Moab with tribute money.

There were 700 choice men who were left-handed among all these people; all could sling a stone at a hair and not miss.
