Chapters 27:1-4
Revised Version 1885
1And the Lord spake unto Moses, saying,
2Speak unto the children of Israel, and say unto them, When a man shall accomplish a vow, the persons shall be for the Lord by thy estimation.
3And thy estimation shall be of the male from twenty years old even unto sixty years old, even thy estimation shall be fifty shekels of silver, after the shekel of the sanctuary.
4And if it be a female, then thy estimation shall be thirty shekels.
