MISHNAH: Where were these prostrations? Four in the North, four in the South, three in the East, and two in the West, corresponding to the thirteen gates.
The Southern gates close to the West: the Upper Gate, the Fuel Gate, the Firstborns’ Gate, the Water gate. And why was it called Water Gate? For there they bring in the phial of water for the water libation on Tabernacles. Rebbi Eliezer ben Jacob said, the water will drizzle in the future from under the threshold
Opposite them in the North, close to the West, the Jechoniah gate, the Sacrifice gate, the Women’s gate, the Song’s gate. And why was it called the Jechoniah gate? For through it Jechoniah left in his deportation. In the East the Nikanor gate, which had two small entrances, one to the right and one to the left. And two in the West which had no names.
