The phrase left-handed
literally reads, restricted in the right hand.
Does that mean he is left-handed? Perhaps, but there is great debate regarding the meaning of this phrase. Some take the phrase to refer to left-handedness.1 Others believe it refers to a physical handicap.2 Still others contend it refers to ambidexterity.3 Regarding this last option, the Septuagint (the Greek translation of the Old Testament) translates this as ambidextrous.
In Judges 20:16, seven hundred Benjaminites are described as Ehud is. But they use slings, which requires both hands. And if we read 1 Chronicles 12:2, we read of Benjaminites again, who could shoot arrows and sling stones with either the right or the left hand
(and there the actual Hebrew word for left-handed
is used). Perhaps, then, the Benjaminites purposely trained their young men to be ambidextrous. At least Ehud is ambidextrous, it seems; he may have deliberately hampered his right hand in order to train himself to be ambidextrous.
Regardless, it is quite ironic for a Benjaminite not to be using his right hand at all, for Benjamin
literally means “son of the right hand.
15 Then the people of Israel cried out to the LORD, and 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.
