'Lord' in the Bible

And Joshua the son of Nun, the attendant of Moses, one of his young men, answered and said, My lord Moses, forbid them!

Then Aaron said to Moses, Alas, my lord, I beseech thee, lay not this sin upon us, wherein we have been foolish, and have sinned!

And now, I beseech 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 spoke to Moses, saying, Thy servants will do as my lord commands.

but thy servants will pass over, every one armed for war, before Jehovah to battle, as my lord says.

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