The point you made reminds of... You make the point that in the bible there is nothing ill spoken of about Joseph. This reminds me of Daniel. In addition to living pure lives, there is a marked resemblance between the two. They had divine dreams; they were carried away captive in their youth; they were unjustly persecuted; and through the interpretation of dream, were exalted to rulership.
Keep up the good work.
Keep up the Good Work! I like the connection you made between Pharaoh's dream and the Mad Cow disease. All answers are in the Bible. Just as the thought of cows eating cows was troubling then, it is still troubling now; for there is nothing new under the sun.
