'Valley gate' in the Bible

Uzziah also built towers in Jerusalem at the Corner Gate, the Valley Gate, and at the corner buttress [of the wall], and fortified them.

So I went out at night by the Valley Gate toward the Dragon’s Well and to the Refuse Gate and inspected the walls of Jerusalem which were broken down and its gates which were consumed by fire.

So I went up at night by the ravine [of Kidron] and inspected the wall; then I turned back and entered [the city] by the Valley Gate, and returned.

Hanun and the inhabitants of Zanoah repaired the Valley Gate. They built it and set up its doors with its bolts and its bars, and repaired a thousand cubits (1,500 ft.) of the wall as far as the Refuse Gate.
