Othniel

lion of God, the first of the judges. His wife Achsah was the daughter of Caleb (Josh 15:16; 15:17; Judg 1:13). He gained her hand as a reward for his bravery in leading a successful expedition against Debir (q.v.). Some thirty years after the death of Joshua, the Israelites fell under the subjection of Chushan-rishathaim (q.v.), the king of Mesopotamia. He oppressed them for full eight years, when they "cried" unto Jehovah, and Othniel was raised up to be their deliverer. He was the younger brother of Caleb (Judg 3:8; 3:9-11). He is the only judge mentioned connected with the tribe of Judah. Under him the land had rest forty years.
