'Let Us' in the Bible

The servants of the king of Aram said to him, "Their gods [are] gods of the mountains, therefore they were stronger than we. Let us fight with them in the plain; surely we will be stronger than they.

Then his servants said to him, "Please now, we have heard that the kings of the house of Israel are kings of mercy. Let us now put sackcloth on around our waists and ropes on our heads. Then let us go out to the king of Israel. Perhaps {he will let you live}."
