1 Samuel 1:11 - Clarke's commentary and critical notes on the Bible

And she vowed a vow, and said, O LORD of hosts, if thou wilt indeed look on the affliction of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid a man child, then I will give him unto the LORD all the days of his life, and there shall no rasor come upon his head. I will give him unto the Lord - Samuel, as a descendant of the house of Levi, was the Lord's property from twenty-five years of age till fifty; but the vow here implies that he should be consecrated to the Lord from his infancy to his death, and that he should not only act as a Levite, but as a Nazarite, on whose head no razor should pass.
