'Let Us' in the Bible

And Peter answering said to Jesus, Lord, it is good we should be here. If thou wilt, let us make here three tabernacles: for thee one, and for Moses one, and one for Elias.

But the husbandmen, seeing the son, said among themselves, This is the heir; come, let us kill him and possess his inheritance.

Arise, let us go; behold, he that delivers me up has drawn nigh.

But the rest said, Let be; let us see if Elias comes to save him.
