ksh execute command containing double quotes

How do I execute a command containing a double quote ?
I pass a variable to grep that contains spaces, so I need to quote it,
but it does not work.

#!/usr/bin/ksh
set -x
txt='"next to"'
cmd="grep $txt ~dpearso5/file2"
echo $cmd
$cmd

This is the error I get:
+ grep "next to" ~dpearso5/file2
grep: 0652-033 Cannot open to".
grep: 0652-033 Cannot open ~dpearso5/file2.

Try this:

#!/usr/bin/ksh
txt="next to"
cmd="grep \"$txt\" ~dpearso5/file2"
eval $cmd

Regards.
