Is there a genetic link to Benjamite lefties?
The Hebrew Bible mentions left-handed people on three occasions: the story of Ehud’s assassination of the Moabite king (Judges 3:12–30), the 700 Benjamites who could use the sling with deadly accuracy (Judges 20:16) and the two-dozen ambidextrous warriors who came to support David in Hebron (1 Chronicles 12:2). All of these stories of left-handed people in the Bible appear in military contexts, and, curiously, all involve members of the tribe of Benjamin.
In a Biblical Views column in the May/June 2013 issue of Biblical Archaeology Review, professors Boyd Seevers and Joanna Klein ask the question, “Were these warriors from the tribe of Benjamin left-handed by nature or nurture?” Citing studies in the genetics of left-handedness and Biblical texts, Seevers and Klein show that it may have been a bit of both.
Benjamites may have been genetically disposed to left-handedness at birth, but the trait may also have been encouraged in soldiers to give them a strategic advantage in combat—somewhat like left-handed baseball pitchers today—against right-handed opponents who were unaccustomed to fighting “lefties.” Warriors from the tribe of Benjamin might have been trained to be equally or more effective with their left hands.
Then again, perhaps the Biblical writers simply enjoyed a bit of word play. The name Benjamin means “son of (my) right hand.” Perhaps the irony of left-handed “sons of right-handers” caused the Biblical authors to take note in these cases.
For more about the tribe of Benjamin, left-handedness in the Bible, and the genetics of left-handedness, see Boyd Seevers and Joanna Klein, Biblical Views: “Left-Handed Sons of Right-Handers” in the May/June 2013 issue of Biblical Archaeology Review.
