Еврейская мысль к Шофтим 3:31

וְאַחֲרָ֤יו הָיָה֙ שַׁמְגַּ֣ר בֶּן־עֲנָ֔ת וַיַּ֤ךְ אֶת־פְּלִשְׁתִּים֙ שֵֽׁשׁ־מֵא֣וֹת אִ֔ישׁ בְּמַלְמַ֖ד הַבָּקָ֑ר וַיֹּ֥שַׁע גַּם־ה֖וּא אֶת־יִשְׂרָאֵֽל׃ (ס)

За ним был Шамгар, сын Анафа, поразивший Филистимлян шестьсот человек воловьим рогом; и он также спас Израиль.

Midrash Tanchuma on Parshat Acharey Mot writes: G-d said to Israel, "in the past you have been helped by means of human beings; in Egypt by Moses and Aaron; in the days of Sisera by Barak and Deborah; against the Midianites by Shamgar etc. throughout the period of the judges. Because G-d employed a human being as His instrument in all of these salvations, the salvation did not last, and you became enslaved again and again. In the future however, I MYSELF will be your salvation, and you will never again be subjugated." This is the meaning of Isaiah 45,17, "Israel will be saved by the Lord, an eternal salvation."
