'Us' in the Bible

If they say, Come with us, Let us lay wait for blood; Let us lurk privily for the innocent without cause;

Let us swallow them up alive as Sheol, And whole, as those that go down into the pit;

Thou shalt cast thy lot among us; We will all have one purse:

Come, let us take our fill of love until the morning; Let us solace ourselves with loves.
