Shofetim 11:36-38

Orthodox Jewish Bible

³⁶ And she said unto him, Avi, if thou hast opened thy mouth unto Hashem, do to me according to that which hath proceeded out of thy mouth; forasmuch as Hashem hath taken vengeance for thee of thine enemies, even of the Bnei Ammon.

³⁷ She said unto her av, Let this thing be done for me; let me alone two chodashim, that I may go up and down upon the hills, and bewail betulai (my virginity), I and my friends.

³⁸ And he said, Go. And he sent her away for two chodashim; and she went with her companions, and bewailed her betulim (virginity) upon the hills.
