Proverbs 31:2

Can a woman forget her sucking child, that she should not have compassion on the son of her womb? yes, they may forget, yet I will not forget thee.

And she vowed a vow, and said, O LORD of hosts, if thou wilt indeed look on the affliction of thy handmaid, and remember me, and not forget thy handmaid, but wilt give to thy handmaid a male child, then I will give him to the LORD all the days of his life, and there shall no razor come upon his head.
