Couple of things.

in is not a variable in the for num in loop.
I wouldn't use num in the loop as you have it declared for an array. Basically accessing $num will access element 0 of the array.

What about :-

Code:
#!/bin/bash

declare -a num
declare -a words

num=(1 2 3 4 5 6 7)
words=(one two three four five six seven)

for var in ${num[@]}
do
        echo ":${num[$var]}: :${words[$var]}:"
done

That's without any testing. Also you will hit a problem as 1 and one will be assigned to element 0 of the array and not element 1.

I've just got a meeting but will check back and test later. It may get you started though
