Then they came to the Fountain Gate, opposite to the Pool of Siloam, and here they descended by steps in the Tower of Siloam.

They probably came down in order that they might dedicate the buildings over the Pool of Siloam and the Dragon Well, and then they climbed to the top of the wall again, by the steps that went up to that part of Jerusalem called the City of David.

From thence Ezra's procession moved on to the eastern wall, where they were to meet the other party.
Nehemiah's company, on leaving the Valley Gate, turned northward, passed the Tower of the Furnaces, went across the Broad Wall, which was almost the only piece of the old wall still standing, passed the Gate of Ephraim, the Old Gate, the Tower of Hananeel, the Tower of Meah, the Sheep Gate, and so down to the temple, and the gate named the Prison Gate, because it opened upon a street leading to the court of the prison.
Then, somewhere near the Water Gate, the two processions met, and marched together into the court of the temple, the two bands now joining together in a united glorious strain, whilst the two companies of singers formed again one enormous united choir, and filled the temple courts with their harmonious song.
'So stood the two companies of them that gave thanks in the house of God,' xii.

40.
Not a voice was silent, there was no idle person in the choir.

Headed by their choir-master they did their utmost to praise the Lord.
'The singers sang loud, with Jezrahiah their overseer.' Nor were the musical people the only ones who showed their joy that happy day.
