And there is a difference between when the noun רצון (desire) comes alone or when the verb רצה (desire) comes alone, and when after רצה comes the word לו or לכם: any place where it says לא ירצה alone, the sacrifice is completely invalid. And any place where it saysלא ירצה לכם (it shall not be accepted for you) – it means that He wants the offering to fulfill the obligation of the owner, that they are desired and valid slaughters, but they are not offerings that fulfill the obligation of the owner. Or whenever it says, ונרצה לו (it shall be accepted for him), it means that the offering fulfills the obligation of the owner.

The language לא ירצה will only fall on animals consecrated for the altar, not on items consecrated for Temple maintenance.
