Kak trevòga, tak do Bòga

I have a question:

In the book Comrade Don Camillo, near the very end of the story, Don Camillo hears these words:

Kak trevòga, tak do Bòga

which are later translated as:

In dire extremity, man remembers his God.

I would like to know whether that is Russian or another language, and if that translation is satisfactory - if there is a literal one I would also like to know that.

Thanks very much...
