Both are mentioned as adversaries of the Jewish people, and are mentioned in various sources, but always separately. Amalek is first mentioned in Shemot Ch 17 and several times in Neviim, while Gog and Magog are mentioned in Ezekiel Ch 38.
Is there any sort of relationship between them ? Are they somehow related, or is one descended from the other ? Will the Jewish people have to face both before the Messianic Age ?
