'Let Us' in the Bible

From where do I have meat to give all these people? They weep before me, saying, 'Give us meat and let us eat!'

And Caleb stilled the people before Moses, and said, Let us go up at once, and possess it; for we are well able to overcome it.

And they said one to another, Let us make a captain, and let us return into Egypt.

Let us pass, I pray thee, through thy country: we will not pass through the fields, or through the vineyards, neither will we drink of the water of the wells: we will go by the king's high way, we will not turn to the right hand nor to the left, until we have passed thy borders.

The {Israelites} said to him, "We will go up on the main road, and if we and our livestock drink your water, we will pay [for it]. It is only a small matter; let us pass through on our feet."

Then Israel gave voice to this song: Come up, O water-spring, let us make a song to it:

Let us pass through thy land; we will not turn into the fields, or into the vineyards; we will not drink water out of the wells; on the king's road will we go until we have passed thy border.
