Vayikra 27:1-3

Orthodox Jewish Bible

27 And Hashem spoke unto Moshe, saying,

² Speak unto the Bnei Yisroel, and say unto them, When a man shall articulate a neder, the nefashot shall be for Hashem by thy evaluation.

³ And thy evaluation shall be of the zachar from esrim shanim even unto shishim shanah, even thy evaluation shall be fifty shekels kesef, after the shekel HaKodesh.
