²  Speak to the children of Israel, and say to them, When a man shall make a singular vow, the persons [shall be] for the LORD, by thy estimation.

³  And thy estimation shall be, of the male from twenty years old even to sixty years old, even thy estimation shall be fifty shekels of silver, after the shekel of the sanctuary.
