This is the name of two biblical men.
Othniel ben Kenaz
The Spirit of the Lord came upon him, and he judged Israel. When he went out to war, the Lord gave Cushan-rishathaim king of Mesopotamia into his hand, so that he prevailed over Cushan-rishathaim. —Judges 3:10 NASB
“He is the only judge mentioned connected with the tribe of Judah. Under him the land had rest forty years.
He is the son of Kenaz, younger brother of Caleb (Judges 3:8,9-11). His wife Achsah was the daughter of Caleb (Joshua 15:16,17; Judges 1:13). He gained her hand as a reward for his bravery in leading a successful expedition against Debir.
Some thirty years after the death of Joshua, the Israelites fell under the subjection of Chushan-rishathaim, 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.” ——Mathew G. Easton, Easton’s Bible Dictionary, with editing by Paul S. Taylor
Othniel, ancestor of Heldai
The twelfth for the twelfth month was Heldai the Netophathite of Othniel; and in his division were 24,000. —1 Chronicles 27:15 NASB
