[If] blood from unblemished [offerings mixed] with blood from blemished [offerings], it should be poured into the canal. [If] a cup [of blood became mixed up] among [other] cups [of blood] — R’ Eliezer says: [If] one cup was offered, they should offer all the cups; but the Sages say: Even if all [the cups] but one were offered, it should be poured into the canal.

[If] those [bloods] which are applied below mixed with those [bloods] which are applied above — R’ Eliezer says: Let him apply [the blood] above and view the lower [blood] which is above as if it were water; and [let him then] return and apply it below. But the Sages say: Let them be poured into the canal. But if he did not take counsel and applied [the blood above], it is valid.
