'Lord' in the Bible

But ye profane it, in that ye say, The table of the Lord is polluted; and the fruit thereof, his food, is contemptible.

Yea, cursed be the deceiver, who hath in his flock a male, and voweth and sacrificeth unto the Lord a corrupt thing; for I am a great King, saith Jehovah of hosts, and my name is terrible among the nations.

Behold, I send my messenger, and he shall prepare the way before me; and the Lord whom ye seek will suddenly come to his temple, and the Angel of the covenant, whom ye delight in: behold, he cometh, saith Jehovah of hosts.
