פירוש על מדות 3:2

ובקרן מערבית דרומית – a cubit below the foundation, there were two perforations.

At the southwestern corner [of the foundation] there were two openings like two small nostrils through which the blood which was poured on the western side of the foundation and on the southern side flowed down till the two streams became mingled in the channel, through which they made their way out to the Kidron wadi. The blood of all sacrifices was either drained on the western side of the foundation (see Zevahim 5:1-2) or on the southern side (Zevahim 5:3). The blood would drain out through two holes shaped like nostrils, and then flow down to the channel that flowed through the Temple Courtyard. From there the blood would be flushed out to the Kidron wadi that flows below the Temple Mount.

שהדמים הניתמים על יסוד מערבי – as, for examples the remnants of the blood of the inner sin-offerings, which are afrer all of he gifts, he would pour the remnants of the blood on the western foundation.

ועל יסוד דרומי – the remnants of the blood of the outer [sacrifices (see Tractate Zevakhim, Chapter 5, Mishnayot 1-3).

יורדין – on the path of those perforations and mix in the water channel that is in the Temple court, an from there leave to the Kidron Valley. And the owners of gardens would purchase them from the treasures to manure the land (see Tractate Yoma, Chapter 5, Mishnah 6 and Tractate Taanit, Chaptet 4, Mishnah 1).
