'Let Us' in the Bible

The inhabitants of one [city] will go to another, saying, “Let us go at once to ask the favor of 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.”’”
