Ladyjean suggested:

I have been told that the Hebrews circumcised their sons, because men went into battle in the buff. Hebrews were circumcised so that they could distinguish themselves from their adversaries, who were also nude.

Sounds suspiciously like Urban Legend to me, Ladyjean. Sort of similar to the "pluck yew" story for why we have the insulting middle finger signal.
