'Us' in the Bible

Hear this word, ye kine of Bashan, that are in the mountain of Samaria, which oppress the poor, which crush the needy, which say to their masters, Bring, and let us drink.

Ye which rejoice in a thing of nought, which say, Have we not taken to us horns by our own strength?

All the sinners of my people shall die by the sword, which say, The evil shall not overtake nor prevent us.
