'Lord' in the Bible

"Lord Yahweh, you have begun to show your servant your greatness, and your strong hand: for what god is there in heaven or in earth, that can do according to your works, and according to your mighty acts?

I prayed to Yahweh, and said, "Lord Yahweh, don't destroy your people and your inheritance, that you have redeemed through your greatness, that you have brought forth out of Egypt with a mighty hand.

For Yahweh your God, he is God of gods, and Lord of lords, the great God, the mighty, and the awesome, who doesn't respect persons, nor takes reward.
