The Hebrew atar (אָטַר) means 'to shut' or 'to close,' and by extension describes a person who is 'shut' in one hand — i.e., left-handed (bound or restricted in the right hand). This root appears in Judges to describe the elite left-handed Benjaminite warriors, including the judge Ehud.
The left-handed warriors of Benjamin — called men who were atar in their right hand — illustrate a profound biblical theme: God uses what the world considers a disadvantage. Left-handedness in the ancient Near East was often seen as the 'weaker' or 'sinister' side, yet Ehud's left-handedness was precisely the quality God used to deliver Israel (Judges 3). The 700 left-handed slingers of Benjamin who could hit a hair without missing were counted as elite troops. What seems like limitation becomes the instrument of divine victory — a truth echoed in Paul's 'when I am weak, then I am strong' (2 Cor 12:10).
