The Hebrew proper name Echud (אֵחוּד) likely means "united" or "strong", related to the root echad (one, united, H259). Ehud was the second judge of Israel, a Benjaminite who delivered Israel from eighteen years of Moabite oppression under King Eglon.
Ehud's story (Judges 3:15–30) is one of Scripture's most unexpected accounts of deliverance. He was left-handed — itter yad yemino ("bound/restricted in his right hand") — an ironic detail since "Benjamin" means "son of the right hand." His left-handedness allowed him to conceal a short double-edged sword on his right thigh, undetected by Eglon's guards. After delivering Israel's tribute, he returned alone with the message: "I have a secret message for you, O king." The rest is a darkly comic tale of liberation. God uses the unexpected, the overlooked, and the "wrong hand" to accomplish His purposes — no human limitation disqualifies someone from being used by God.
