Shallecheth

(overthrow), The gate, one of the gates of the “house of Jehovah.” (1 Chronicles 26:16) It was the gate “to the causeway of the ascent.” As the causeway is actually in existence, the gate Shallecheth can hardly fail to be identical with the Bab Silsileh or Sinsleh which enters the west wall of the Haram about 600 feet from the southwest corner of the Haram wall.

I.e., “the gate of casting out,” hence supposed to be the refuse gate; one of the gates of the house of the Lord, “by the causeway of the going up” i.e., the causeway rising up from the Tyropoeon valley = valley of the cheesemakers (1 Chr. 26:16).
