'Let Us' in the Bible

And the inhabitants of one city shall go to another, saying, Let us go speedily to pray before the LORD, and to seek the LORD of hosts: I will go also.

Thus says the Lord of hosts, ‘In those days ten men [as representatives] from all the nations will grasp the robe of a Jew, saying, “Let us go with you, for we have heard that God is with you.”’”
