The relative values of the persons appear to be regulated according to an estimate of the probable value of their future work:

Ages Male Female From a month to five years of age 5 shekels 3 shekels From five years to twenty of age 20 shekels 10 shekels From forty years to sixty of age 50 shekels 30 shekels Sixty years of age and older: 15 shekels 10 shekels

As regards the shekel of the sanctuary, see Exodus 38:24 note.

And if it be a female - The woman, at the same age, vowed unto the Lord, might be redeemed for thirty shekels, 4. 10s. sterling, a little more than one half of the value of the man; for this obvious reason, that a woman, if employed, could not be of so much use in the service of the sanctuary as the man, and was therefore of much less value.

And if it be a female,.... That is, of the same age, full twenty years of age, and not more than sixty:

then thy estimation shall be thirty shekels; about three pounds ten shillings of our money, the price of a servant, Exodus 21:32; the reason of this difference of estimation between a man and a woman is, because the woman is the weaker vessel, and her labour and service of less importance and worth, such as spinning, washing, &c.

And if it be a female, then thy estimation shall be thirty shekels.

27:4 Thirty shekels - Less than the man's price, because she is inferior to him both in strength and serviceableness.

27:1-13 Zeal for the service of God disposed the Israelites, on some occasions, to dedicate themselves or their children to the service of the Lord, in his house for life. Some persons who thus dedicated themselves might be employed as assistants; in general they were to be redeemed for a value. It is good to be zealously affected and liberally disposed for the Lord's service; but the matter should be well weighed, and prudence should direct as to what we do; else rash vows and hesitation in doing them will dishonour God, and trouble our own minds.
