How do I take every 3rd number from a text file?

Hi,

I've been reading in text files using the following command:

ReadList["file.txt", Word]

However, now I only want to read in every 3rd number, starting with
the valueI specify.

For example, say I had these values:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

How would I read in every third number, starting with the second
integer?  So the result would look like this:

1, 4, 7
