'Let Us' in the Bible

And he said to Judah, Let us build these cities, and surround them with walls and towers, gates and bars, while the land is yet before us; for we have sought Jehovah our God; we have sought him, and he has given us rest on every side. And they built and prospered.

And Amaziah king of Judah took counsel, and sent to Joash the son of Jehoahaz, the son of Jehu, king of Israel, saying, Come, let us look one another in the face.
