The meek shall inherit (fwd)

This came off of another list, and the author says some things I've never 
heard before concerning the Greek of this verse.  I'm still a relatively 
new student to Greek, and I was wondering if one of the more learned 
brothers or sisters could address the Greek of Jesus' "meek."

2. re "the meek share inherit the earth". An interesting quote cause I
took (100 years ago) a theology course at university and the
clergyman/teacher of the day...an intellectual who read Greek.....told me
that "meek" did not mean wimpy at Jesus' time. It meant "street-wise".
Therefore, if you are on the ball you will inherit the earth, not if
you lay down and let em walk over you.
