"What we do know about Amalek is based upon the various episodes in history that discuss Amalek. Amalek is the same numerical value as Doubt (Safek), hence the idea that Amalek is rooted in Doubt. Essentially, they created the initial Doubt in the world about G-d's ability to oversee the details of the Jewish People. By attacking the children of Israel without warrant, after the world had witnessed all the miracles of Egypt and the Sea, they cast aspersions on the sanctity of Israel's relationship with G-d. That is what the Midrash comments 'they cooled off the bath water,' meaning, Amalek created doubts in the minds of the nations and the Jewish People. The Almighty's Throne will not be restored to its full glory until all Doubt about His Omnipotence is eradicated. This was the task that King Shaul of the tribe of Benyamin was to achieve and didn't. Until further notice, this remains an ongoing obligation for the descendants of Israel: removing Amalekite Doubt." ~ R' Yehudah Abrams
WIKIPEDIA: According to the Bible, Galilee was named by the Israelites and was the tribal region of Naphthali and Dan, at times overlapping the Tribe of Asher's land.
