'Let Us' in the Bible

They all said to each other, "Come, let us cast lots, that we may know for whose cause this evil is on us." So they cast lots, and the lot fell on Jonah.

Therefore they cried to the LORD, and said, "We beg you, LORD, we beg you, let us not perish for this man's life, and do not lay on us innocent blood; for you, LORD, have done as it pleased you."
