"The word "almah" has been translated as "young woman" instead of "virgin"."
We're probably lucky they're not translating it into "person" this year.
These translators--who are doing the Devil's work and should be ejected vigorously from the church--are suffering from the virus of Relativism, which is laying waste to western culture. Since virtually everything in the Bible is the exact opposite of relativist, we can expect to see a lot more such transmogrification in the future. By the time these cretins are through, the "Bible" will be meaningless.
Unless Relativism is beaten back into oblivion, Christianity and Judaism are doomed. The only way to prevent that, is to fight to retain the meaning of words and pray that Relativism falls out of fashion.
Today, it ain't lookin' too good.
