The Gate Shallecheth
Fausset's Bible Dictionary [1]
("overturning".) 1 Chronicles 26:16. Botcher translated "refuse door." The gate was at the road of ascent from the middle valley of Jerusalem to the western side of the temple court. This ascending causeway is still existing, though hidden by the houses in the valley. So the Shallecheth gate is the bab Silsileh or Sinsleh, which enters the western wall of the Haram area opposite the southern end of the platform of the Dome of the Rock, 600 ft. from the S.W. corner of the Haram wall. (See Temple ; JERUSALEM.)

shal´ḗ - keth , sha - lē´keth ( שׁלּכת שׁער , sha‛ar shallekheth , i.e. as in margin, "Casting forth"): A gate of the temple "at the causeway that goeth up" ( 1 Chronicles 26:16 ) - probably an ascent from the Tyropoeon Valley to the West of the temple. It has been supposed on account of the meaning of the name that the ashes and offal of the temple were cast forth there, but this is very unlikely - they were thrown into the Kidron valley to the East or Southeast. The Septuagint has παστοφορίον , pastophorı́on , which seems to point to a building with chambers; in consonance with this Cheyne reads in the Hebrew לשׁכּות , lishkōth , "(of) the chambers."
