How to pass variables from shell script to sqlplus

How can I pass in newValue to sqlplus from shell?  It keeps erroring out due to $1 and like characters which are a random value assigned to newValue in database.

newValue= $2a$10$1Qect



for db_user in db1/user1 db2/user2 db3/user3 db4/user4 db5/user5 db6/user6
  db=`echo $db_user | cut -f1 -d/`
  user=`echo $db_user | cut -f2 -d/`
  $ORACLE_HOME/bin/sqlplus ${user}/${common_pass}@${db} << EOF
select * from tab
where idValue = $newValue;
