Wrench Bash For Loop Help

This is a short program I wrote to search through a directory and move files containing the keyword to a folder.
Code:
#!/bin/bash

echo 'What is the directory?'
read DIR
echo -e '\n'

echo 'What is the keyword?'
read KEY

echo -e '\n'

cd $DIR
rmdir 'relevant_files'
mkdir 'relevant_files'

for entry in 'grep -ilr $KEY $DIR'; do
    echo $entry
    mv $entry 'relevant_files'
done

The main problem I'm having with is the for loop.
Code:
for entry in 'grep -il $KEY $DIR'; do
    echo $entry
    mv $entry 'relevant_files'
done

My question is, how would I make the for loop entries equal to each file grep comes up with in the directory?

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a file name containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
