He came to the ox and he-goat which were to be burned. He tore them and removed their sacrificial parts. He put them in a plate and burned them upon the [Outer] Altar. He intertwined [the limbs of the ox and he-goat] into twists and removed them to the place of burning.  And from when do these [people] contaminate clothing? From when they go outside the wall of the Courtyard. R' Shimon says: From when the fire catches onto the greater part of [the limbs].

They said to the Kohen Gadol, “The he-goat has reached the wilderness.” And how did they know that the he-goat had reached the wilderness? They set up watch-posts and waved cloths, and thus they knew that the he-goat had reached the wilderness.  R' Yehudah said: But they had a dependable signal: From Jerusalem to the place of the he-goat's sharp peak was three mil; they walked a mil, returned a mil, and tarried for [the time needed to walk] a mil. Thus they knew that the he-goat had reached the wilderness.  R' Yishmael says: But did they not have another sign? A strip of red wool was tied atop the Temple entrance, and when the he-goat reached the wilderness the strip of wool whitened, as it has been said: [Even] if your sins will be like crimson thread they will become white as snow.
