From The Talmud And Hebraica

We have little to certify as to the situation of this place: only we learn this of Josephus concerning Cana, that it was such a distance from Tiberias, as he could measure with his army in one night. For when word was brought him by letters, that the enemy Justus had endeavoured to draw away the Tiberians from their fidelity towards him, "I was then (saith he) in a town of Galilee, called Cana: taking, therefore, with me two hundred soldiers, I travelled the whole night, having despatched a messenger before, to tell the Tiberians of my coming: and, in the morning, when I approached the city, the people came out to meet me," &c.

He makes mention, also, of Cana, in the same book of his own Life, in these words; "Sylla, king Agrippa's general, encamping five furlongs from Julias, blocked up the ways with guards, both that which leads to Cana, and that which leads to the castle Gamala." But now, when Julias and Gamala, without all doubt, were beyond Jordan, it may be inquired whether that Cana were not also on that side. But those things that follow seem to deny this: for he blocked up the ways, "that by this means he might shut out all supplies that might come from the Galileans." Mark that, that might come from the Galileans; that is, from Cana, and other places of Galilee about Cana.

That Julias which Sylla received was Julias Betharamphtha (of which afterward), which was seated on the further bank of Jordan, there where it is now ready to flow into the sea of Gennesaret. Therefore, Cana seems, on the contrary, to lie on this side Jordan; how far removed from it we say not, but we guess not far; and it was distant such a space from Tiberias as the whole length of the sea of Gennesaret doth contain.
