Tosefta do Kapłańska 16:20

Said Rabbi Yosei, this is the sign: Anything taken out from inside to be placed outside, is taken from that which is adjacent to the inside, and anything taken from inside to be placed outside, is placed on that which is adjacent to the inside. [If] he took some of the blood of the bull from inside to outside, [or] some of the blood of the goat from inside to outside, the inside [blood] ascended [to Heaven] for him and the outside [blood] did not ascend for him. [If] he sprinkled some of the sprinklings that are [required to be performed] inside, and poured out the blood, he should bring another and start from the beginning on the Curtain. [If] he sprinkled some of the sprinklings [that are required to be performed] on the Altar and poured out the blood, even though he did not place it next to the base [of the Altar], he fulfilled [his obligation], as it is said (Lev. 16:20), "When he has finished atoning [etc.]." If he has effected atonement, he has completed [his service], the words of Rabbi Akiva. Rabbi Yehuda says, if he has completed [his service], he has effected atonement. [Failure to] pour out the blood on the base is not required [to effect atonement]; and anything [that is poured out] against the base fulfills [the obligation], as it is said (ibid.), "When he has finished atoning [etc.]."

[If] the goat to be sent away died before the blood of the first [goat] was sprinkled, even though [the High Priest] did not confess on it, he fulfilled [his obligation], as it is said (Lev. 16:10): "[The goat ... shall be left] standing alive." Until when must it remain alive? Until he has finished the atonement of the Holy (see Lev. 16:20), the words of Rabbi Yehuda. Rabbi Shimon says, until the time of the confession.
