The short answer are those who oppose Israel and YHWH. They are enemies of Israel and YHWH! YHWH will war against them eternally for what they did to Israel as they left Egypt and for what they are still doing against Israel through terrorism. The nation of Amalek descended from Abraham, it's founder being the grandson of Esau. Think of Esau, Amalekites, Ishmael, these were and are Muslim nations who hate Israel and those that support Israel, there is a spirit behind them as well that kills, steals and destroys. We as believers need to do our part in this battle and support Israel as they battle Hamas/Amalekites. Hamas is modern day Amalekites.
