Proverbs 31:2

Will a woman give up the child at her breast, will she be without pity for the fruit of her body? yes, these may, but I will not let you go out of my memory.

And she made an oath, and said, O Lord of armies, if you will truly take note of the sorrow of your servant, not turning away from me but keeping me in mind, and will give me a man-child, then I will give him to the Lord all the days of his life, and his hair will never be cut.
