|Easton's Bible Dictionary|
The transliteration of the Hebrew word tsebha'oth, meaning "hosts," "armies" (Romans 9:29; James 5:4). In the LXX. the Hebrew word is rendered by "Almighty." (See Revelation 4:8; Comp. Isaiah 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.
Noah Webster's Dictionary
1. (n. pl.) Armies; hosts.
2. (n. pl.) Incorrectly, the Sabbath.
