Loop exits and go to next line in bash

I want to iterate the first line in "profile" to the first line in "arn" and then 2nd line "profile" to 2nd line in "arn", 3rd line in "profile" to 3rd line in "arn"

But my script check the first in profile file and loop all the contents in "arn" file. After finishing it will got to next line in "profile" and loop all the content in "arn"

#!/bin/bash

for profile in `cat ../../.aws/config|grep 'profile'`
do
        for arn in `cat policy_arn`
        do
                 aws --profile ${profile} iam delete-policy  --policy-arn ${arn}
        done
done

cat policy_arn

arn:aws:iam::37928052:policy/PointPolicy
arn:aws:iam::56433041:policy/PointPolicy
arn:aws:iam::18225202:policy/PointPolicy
arn:aws:iam::908231278:policy/PointPolicy
arn:aws:iam::441043922:policy/PointPolicy
arn:aws:iam::227661653:policy/PointPolicy

profile

dev-ops
pro-ops
qc-ops

OUTPUT

should be

first loop arn=arn:aws:iam::37928052:policy/PointPolicy and profile=dev-ops
2. arn=arn:aws:iam::56433041:policy/PointPolicy profile=pro-ops
3. arn=arn:aws:iam::18225202:policy/PointPolicy profile=qc-ops

But what is happening when i run the script is

dev-ops arn:aws:iam::37928052:policy/PointPolicy
dev-ops arn:aws:iam::56433041:policy/PointPolicy
dev-ops arn:aws:iam::18225202:policy/PointPolicy
dev-ops arn:aws:iam::908231278:policy/PointPolicy
dev-ops arn:aws:iam::441043922:policy/PointPolicy
dev-ops arn:aws:iam::227661653:policy/PointPolicy


pro-ops arn:aws:iam::37928052:policy/PointPolicy
pro-ops arn:aws:iam::56433041:policy/PointPolicy
pro-ops arn:aws:iam::18225202:policy/PointPolicy
pro-ops arn:aws:iam::908231278:policy/PointPolicy
pro-ops arn:aws:iam::441043922:policy/PointPolicy
pro-ops arn:aws:iam::227661653:policy/PointPolicy

qc-ops arn:aws:iam::37928052:policy/PointPolicy
qc-ops arn:aws:iam::56433041:policy/PointPolicy
qc-ops arn:aws:iam::18225202:policy/PointPolicy
qc-ops arn:aws:iam::908231278:policy/PointPolicy
qc-ops arn:aws:iam::441043922:policy/PointPolicy
qc-ops arn:aws:iam::227661653:policy/PointPolicy

I have 40+ aws accounts so i will create a loop for "profile" at the same time policy arn should get with the same profile account ID.

How can I achieve the output like this.

You can do this with:

grep 'profile' ../../.aws/config | paste - policy_arn

The paste command joins two files as columns, and here we use - for the first filename to represent it coming from stdin (ie it comes from the pipe). No loop is required.
