Dedication of Samuel by his Mother

And she made a vow, saying, “O LORD of Hosts, if only You will look upon the affliction of Your maidservant and remember me, not forgetting Your maidservant but giving her a son, then I will dedicate him to the LORD all the days of his life, and no razor shall ever touch his head.”

…but Hannah did not go. “After the boy is weaned,” she said to her husband, “I will take him to appear before the LORD and to stay there permanently.”
