And she made a vow, pleading, “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 come over his head.”

But you are to take your holy things and your vow offerings and go to the place the LORD will choose.

You will pray to Him, and He will hear you,and you will fulfill your vows.
