"The transliteration of the Hebrew word tsebha'oth, meaning" "hosts, "armies" (Rom. 9:29; James 5:4). In the LXX. the Hebrew" "word is rendered by "Almighty." (See Rev. 4:8; comp. Isa. 6:3.)" It may designate Jehovah as either (1) God of the armies of "earth, or (2) God of the armies of the stars, or (3) God of the" unseen armies of angels; or perhaps it may include all these ideas.
