'Lord' in the Bible

O Lord Jehovah, thou hast begun to show thy servant thy greatness, and thy strong hand: for what god is there in heaven or in earth, that can do according to thy works, and according to thy mighty acts?

And I prayed unto Jehovah, and said, O Lord Jehovah, destroy not thy people and thine inheritance, that thou hast redeemed through thy greatness, that thou hast brought forth out of Egypt with a mighty hand.

For Jehovah your God, he is God of gods, and Lord of lords, the great God, the mighty, and the terrible, who regardeth not persons, nor taketh reward.
