Judg 3:9

“We frequently find this calling from need in Scripture as well, when we read that on account of their sins, the children of Israel were delivered over by the Lord to their enemies and that, having changed their course because of their domination and savage cruelty, they cried out to the Lord. "And the Lord sent them," it says, "a deliverer named Ehud, the son of Gera, the son of Jemini, who used either hand as if it were his right hand." And again it says, "They cried out to the Lord, who raised up a deliverer for them, Othniel, the son of Kenaz, the younger brother of Caleb, and he freed them." And it said of them in a psalm: "When he killed them, then they sought him, and they turned and at dawn they came to God, and they remembered that God was their helper." And again: "They cried out to the Lord when they were troubled, and he freed them from their distress."Of these three kinds [of calling from need], then, although the first two seem to be supported by better beginnings, nonetheless we find that even on the third level [recorded by the psalmist], which seems inferior and lukewarm, there have been people who are perfect and very fervent in spirit, similar to those who have made an excellent beginning in the Lord's service and have passed the rest of their lives in praiseworthy intensity of spirit. Likewise there are many who have become tepid and have fallen from a higher level and very frequently ended up in tragedy. [Thus], just as it was no drawback to the former that they seem to have been converted not by their own will but by force of necessity, inasmuch as the Lord's kindness furnished the occasion whereby they might feel compunction, likewise their having been converted in some sublime fashion profited the latter nothing whatsoever, because they did not strive to live out the rest of their days accordingly.”

“Saviour. “We must remark, that the man by whom God grants us safety, is styled a saviour,” (St. Augustine, q. 18,) though Christ is the proper and principal Saviour. (Worthington) — Caleb. Septuagint, “the younger son of Cenez, who was the brother of Caleb.” (Haydock) — Othoniel was one of the ancients. If he could not prevent the people from falling into idolatry, he rescued them from it. (Calmet)”

“when the children of Israel cried unto the Lord--In their distress they had recourse to earnest prayer, accompanied by humble and penitent confession of their errors. Othniel--(See on Jos 15:16; Jdg 1:13). His military experience qualified him for the work, while the gallant exploits he was known to have performed, gained him the full confidence of his countrymen in his ability as a leader.”
