'Left handed' in the Bible

And the {Israelites} cried out to Yahweh, and Yahweh raised up for them a deliverer, Ehud son of Gera, a Benjaminite and {a left-handed man}. And the {Israelites} sent a tribute to Eglon king of Moab {through him}.

From all these troops [were] seven hundred well-trained men {who were left-handed}; each one could sling with a stone at a hair and not miss.
