Mishnah Zevachim
[If blood] which requires one application [was mixed] with blood [also] requiring one application, it [the mixture] should be presented with one application. [If blood] which requires four applications [was mixed] with blood requiring four applications, they should be presented with four applications. [If blood] which requires four applications [was mixed] with blood which requires one application: Rabbi Eliezer says: it [the mixture] should be presented with four applications. Rabbi Joshua says: it should be presented with one application. Rabbi Eliezer said to him: Behold, he transgresses the [injunction] not to diminish [from God’s commandment]! Rabbi Joshua said to him: Behold, he transgresses the injunction not to add [to God’s commandments]. Rabbi Eliezer said to him: The injunction not to add applies only where it is by itself. Rabbi Joshua said to him: The injunction not to diminish applies only where it is by itself. Moreover, Rabbi Joshua said: when you make [four] applications you transgress the injunction not to add, and perform an action with your own hands; whereas when you do not make [four] applications you transgress the injunction not to diminish, but do not perform an action with your own hands.
