"Adonoy was with him previously." We learn that he was not with him later. And Yiftoch was afflicted with ulcerations and the loss of his limbs, as it is said,²⁷Below, 12:7. "He was buried in the cities of Gilod."²⁸Individual limbs, like the entire body, require burial. The plural usage, “cities”, teaches that his burial took place in a number of cities—wherever his limbs fell. (Yalkut, ibid.)

And she had not known a man It wishes to say, as he had vowed, so she had done, and she had separated from men.
