'Lord' in the Bible

"But the deceiver is cursed, who has in his flock a male, and vows, and sacrifices to the Lord a blemished thing; for I am a great King," says Yahweh of Armies, "and my name is awesome among the nations."

"Behold, I send my messenger, and he will prepare the way before me; and the Lord, whom you seek, will suddenly come to his temple; and the messenger of the covenant, whom you desire, behold, he comes!" says Yahweh of Armies.
