the LORD of Hosts (Hebrew Yahweh tseba’oth): This name for God is important in Old Testament prophetic writings. Hosts are the angelic forces under God's command. This phrase emphasizes God's power, which cannot be defeated.
the Land of Wickedness: Esau was selfish and showed disrespect for the Lord’s covenant symbols (see Genesis 25:34). The nation of Edom came to represent the pride of a self-centered life (see Jeremiah 49:16). The Edomites also allied with Babylon in destroying Jerusalem (see Psalm 137:7–9; Obadiah 1:10, 12).
