linux shell script to take variables from two different files line by line

Friends

I need to have a shell script which will feed variables from two different files line-by-line. For example, I have two files - permission and file_name.
Contents of permission is -
644
755
....
contents of file_name
/file1
/file2
.....

Now I want 644 permission will be assigned to /file1, 755 permission to be assigned to /file2 and so on.

Please help

Code:
#! /bin/bash
for i in `expr permission`
for k in `cat file_name`
do
chmod $i $k
done

This ends with
Code:
./test: line 3: syntax error near unexpected token `for'
./test: line 3: `for k in `cat file_name`'
