This article, translated from the original is a classic case of the translator repeatedly changing a meaning which reinforces an error. There were no Jews in Egypt during the time apparently being referenced (prior to the Exodus) there were only Israelites. While all Jews were Israelites, most Israelites were not Jews.
The Israelites were gone from Egypt many centuries before the Kingdoms split and the NORTHERN Kingdom was taken into captivity by the Assyrians. The Jews came from the Southern Kingdom. It makes you wonder what else is being mistranslated and referenced as history.
It makes me wonder what kind of pedant continually pounds on his favorite pedantry.
