Malakhim

In Judaism, angels (Hebrew: מַלְאָךְ, romanized: mal’āḵ, lit. 'messenger', plural: מַלְאָכִים mal’āḵīm) are supernatural beings that appear throughout The Tanakh (Hebrew Bible), rabbinic literature, apocrypha and pseudepigrapha, Jewish philosophy and mysticism, and traditional Jewish liturgy as agents of the God of Israel. They are categorized in different hierarchies. Their essence is often associated with fire. The Talmud describes their very essence as fire.
