Judges 11:37

And she said unto her father, Let this thing be done for me: let me alone two months, so long he should delay the paying of his vow, that I may go up and down upon the mountains, far from the haunts of men, and bewail my virginity, I and my fellows, for by the vow of her father she was destined to perpetual virginity, one of the saddest lots that could befall a daughter of Israel, the only child, moreover, through which the house of her father could be continued.
