Abaye, a Jewish sage of the 4th century was quoted as saying; "If these orifices be now opened, the water rushes in from all sides, and the marble floor of the sanctuary is washed clean of the blood of the sacrifices, if it be ever so much, and thus cleansed of itself, and in the easiest manner. There can be, moreover, never a want of water in these artificially constructed tubes, as it is conducted hither FROM A LARGE NATURAL SPRING (ETAM), which to a certainty can never dry...
Tosefta Pesachim, Ch. 3, Par. 12,"How is the Azara cleaned? Seal the area and let the water from the aqueduct enter till it becomes clean like milk."

When he comes to the description of the siege by Titus, AD 70, the Temple with its enclosure, and the tower of Antonia at the north-west angle of the enclosure, having been entirely rebuilt by Herod, BC 17, Josephus says that the design of Titus was
"to take the Temple at the tower of Antonia;" and that for
this
purpose he raised great banks; one of which was at
the tower of Antonia,
and the other at about 20 cubits from it; and that for the
purpose of
obtaining materials or filling up the immense fosse and
ravine to the north of the Temple, he had to bring
them from a great distance; and that
the country all round for a distance of 19 or 12 miles was made
perfectly bare
in consequence.
