I never said that Adinokam visited 666 places. Nor do the verses. And that is exactly the point. Read the entire chapter. Ezra 2. here are some verses:
The children of Elam, a thousand two hundred fifty and four.
The children of Adonikam, six hundred sixty and six.
The children of Bethlehem, an hundred twenty and three.
The men of Anathoth, an hundred twenty and eight.
Elam, Bethlehem, and Anathoth are names of places. I am quite certain that a smart learned man like you will immediately recognize the last two from the Bible.
It lists how many people came from each place. Not how many places they visit. The verse doesn't say anything at all like that.
It would be a good idea to actually read the verses, understand what they say, and afterwards think before you write. When you are done- consider apologizing. There is no need to call other people stupid just because you disagree with them. Even if you are clearly wrong.
