[If blood] requiring one application [to the Altar] mixed with [blood] requiring one application, they should be applied in one application. [If blood] requiring four applications [mixed] with [blood requiring] four applications, they should be applied in four applications. [If blood] requiring four applications [mixed] with [blood] requiring one application — R’ Eliezer says: They should be applied in four applications. R’ Yehoshua says: They should be applied in one application. Said R’ Eliezer to him: But he thereby transgresses [the commandment] (Deut. 13:1): Do not subtract! Said R’ Yehoshua to him: But he thereby transgresses [the commandment] (Deut. 13:1): Do not add! Said R’ Eliezer to him: Do not add applies only when it is by itself. Said R’ Yehoshua to him: Do not subtract applies only when it is by itself. R’ Yehoshua said further: If you make [four] applications you transgress, Do not add, and perform an act; but if you do not make [four] applications, [though] you transgress, Do not diminish, you have not performed an act.
