There were chambers underneath the Court of Israel which opened into the Court of Women, where the Levites used to keep lyres and lutes and cymbals and all kinds of musical instruments. The Court of Israel was a hundred and thirty-five cubits in length by eleven in breadth. Similarly the Court of the Priests was a hundred and thirty-five cubits in length by eleven in breadth. And a row of mosaic stones separated the Court of Israel from the Court of the Priests. Rabbi Eliezer ben Jacob says: there was a step a cubit high on which a platform was placed, and it had three steps each of half a cubit in height. In this way the Court of the Priests was made two and a half cubits higher than that of Israel. The whole of the Court was a hundred and eighty-seven cubits in length by a hundred and thirty-five in breadth. And thirteen prostrations were made there. Abba Yose ben Hanan says: they were made facing the thirteen gates. On the south beginning from the west there were the upper gate, the gate of burning, the gate of the firstborn, and the water gate. And why was it called the water gate? Because they brought in through it the pitcher of water for libation on the festival. Rabbi Eliezer ben Jacob says: in it the water welled up, and in the time to come from there it will come out from under the threshold of the Temple. Corresponding to them in the north beginning in the west were the gate of Yehoniah, the gate of the offering, the women's gate, the gate of song. Why was it called the gate of Yehoniah? Because Yehoniah went forth into captivity through it. On the east was the gate of Nicanor; it had two doors, one on its right and one on its left. There were further two gates in the west which had no special name.
