Left handedness is often seen by the world as weakness.
But when the children of Israel cried unto the LORD, the LORD raised them up a deliverer, Ehud the son of Gera, a Benjamite, a man lefthanded: and by him the children of Israel sent a present unto Eglon the king of Moab. (Judges 3:15 KJV)
The Jewish people cried out to God for Him to send someone to deliver them from the persecution they faced from those who ruled over them. God heard their cries and sent unto them Ehud, whom the Bible specifically states was a left handed man. Often a left handed leader is looked upon as a weak and ineffective; while those (the majority) are right handed and seen as superior and victorious. God seems to be sending a specific message about operating in His strength not human strength when sending Ehud who was a left handed victor.
And Ehud put forth his left hand, and took the dagger from his right thigh, and thrust it into his belly: (Judges 3:21 KJV)
Ehud had a plan for assassinating the King of Moab who had allowed darkness and deceit to rule in his kingdom. Ehud had crafted and honed a sharp dagger to fatally assault the King planning to take his life straightway spilling his innards upon the ground.
Ehud had the opportunity to approach the king who was not suspect of him and did jab him with his left hand spilling his inwards parts upon the ground and bringing quick death upon him. Ehud brought about victory for the Jewish people through God’s strength and power at work within Him according to the will of God upon his life.
