Leviticus 27:1-3

Young's Literal Translation

27 And Jehovah speaketh unto Moses, saying,

² `Speak unto the sons of Israel, and thou hast said unto them, When a man maketh a wonderful vow, by thy valuation the persons [are] Jehovah's.

³ When thy valuation hath been of the male from a son of twenty years even unto a son of sixty years, then hath been thy valuation fifty shekels of silver by the shekel of the sanctuary.
