'What Shall We Do' in the Bible

And the publicans also came to be immersed, and they said to him: Teacher, what shall we do?

And soldiers also asked him, saying: And what shall we do? And he said to them: Take nothing from any one by extortion, nor by false accusation, and be content with your pay.

Then they said to him: What shall we do, that we may work the works of God?

When they heard this, they were pierced to the heart, and said to Peter and the other apostles: Brethren, what shall we do?

saying: What shall we do with these men? For that an evident sign has been done by them, is manifest to all that dwell in Jerusalem, and we can not deny it.
