Numbers 18:16 Meaning and Commentary

Numbers 18:16

And those that are to be redeemed
Which is to be understood not of unclean beasts last mentioned, for they were redeemed with lambs and not with money; and after they were eight days and not a month old, as follows, ( Exodus 13:13 ) ( 22:30 ) ; but of the firstborn of men:

from a month old shalt thou redeem, according to thine estimation:
that is, take the redemption money next mentioned; and though both time and price are fixed, yet said to be according to the estimation of the priest; see ( Leviticus 27:5 Leviticus 27:6 ) ;

for the money of five shekels;
which was about eleven or twelve shillings of our money, and is the price given for the redemption of the firstborn, when the Levites were taken in their stead, ( Numbers 3:47 ) ;

after the shekel of the sanctuary, which [is] twenty gerahs,
(See Gill on Numbers 3:47); of the manner of redeeming the firstborn, (See Gill on Exodus 13:15).

Numbers 18:16 In-Context

14 "You get every Totally-Devoted gift.

15 Every firstborn that is offered to God, whether animal or person, is yours. Except you don't get the firstborn itself, but its redemption price; firstborn humans and ritually clean animals are bought back and you get the redemption price.

16 When the firstborn is a month old it must be redeemed at the redemption price of five shekels of silver, using the standard of the Sanctuary shekel, which weighs twenty gerahs.

17 "On the other hand, you don't redeem a firstborn ox, sheep, or goat - they are holy. Instead splash their blood on the Altar and burn their fat as a Fire-Gift, a pleasing fragrance to God.

18 But you get the meat, just as you get the breast from the Wave-Offering and the right thigh.
