Jehovah Sabaoth is translated as Lord of Hosts or Lord of Powers. Sabaoth means hosts or armies, and combined with the term for Lord, it signifies His control over all armies, whether spiritual or earthly. This compound name is used almost 300 times in Scripture, most often by Isaiah and Jeremiah. It is first used in the story of a man named Elkinah and his wife Hannah who were making their annual pilgrimage to Shiloh.
Now this man used to go up year by year from his city to worship and to sacrifice to the Lord of hosts at Shiloh, where the two sons of Eli, Hophni and Phinehas, were priests of the Lord. 1 Samuel 1:3
