'Lord' in the Bible

And Joshua the son of Nun, the minister of Moses, one of his chosen men, answered and said, My lord Moses, forbid them.

And Aaron said unto Moses, Oh, my lord, lay not, I pray thee, sin upon us, for that we have done foolishly, and for that we have sinned.

And now, I pray thee, let the power of the Lord be great, according as thou hast spoken, saying,

And the children of Gad and the children of Reuben spake unto Moses, saying, Thy servants will do as my lord commandeth.

but thy servants will pass over, every man that is armed for war, before Jehovah to battle, as my lord saith.

and they said, Jehovah commanded my lord to give the land for inheritance by lot to the children of Israel: and my lord was commanded by Jehovah to give the inheritance of Zelophehad our brother unto his daughters.
