'Left handed' in the Bible

When the Israelites cried out for help to the Lord, he raised up a deliverer for them. His name was Ehud son of Gera the Benjaminite, a left-handed man. The Israelites sent him to King Eglon of Moab with their tribute payment.

Among this army were seven hundred specially-trained left-handed soldiers. Each one could sling a stone and hit even the smallest target.
