Judges 3:14

12 The children of Israel again did that which was evil in the LORD’s sight, and the LORD strengthened Eglon the king of Moab against Israel, because they had done that which was evil in the LORD’s sight.

13 He gathered the children of Ammon and Amalek to himself; and he went and struck Israel, and they possessed the city of palm trees.

14 The children of Israel served Eglon the king of Moab eighteen years.

15 But when the children of Israel cried to the LORD, the LORD raised up a savior for them: Ehud the son of Gera, the Benjamite, a left-handed man. The children of Israel sent tribute by him to Eglon the king of Moab.

16 Ehud made himself a sword which had two edges, a cubit in length; and he wore it under his clothing on his right thigh.
