'Let Us' in the Bible

But when the vinedressers saw his son they said to themselves, 'Here is the heir; come on, let us kill him and seize his inheritance!'

Come, get up and let us go. Here is my betrayer close at hand!"

But the others said, "Stop, let us see if Elijah does come to save him!" [Seizing a lance, another pricked his side, and out came water and blood.]
