Judges 11:35

And it came to pass, when he saw her, that he rent his clothes, as a sign of deep distress and mourning, and said, Alas, my daughter! thou hast brought me very low, and thou art one of them that trouble me, literally, "Deeply hast thou caused me to bow, and thou alone art distressing me," unwittingly causing him the depest agony; for I have opened my mouth unto the Lord, and I cannot go back, he could not make his vow unsaid.
