integers in bounds placed as string fails (using ModelsManager)

Hi.

I am trying to do a simple query on my table i have.
i am trying to set a limit and offset but i get errors.

my code i'm running

$app->get('/pictures', function($limit = 10, $offset = 0, $filename = '41232fa061a8a.jpg') use ($app)
{
    #$phql = "SELECT p.id, p.filename, p.age FROM pictures p WHERE p.status = 'active' LIMIT 10 OFFSET 0";
    $phql = "SELECT p.id, p.filename, p.age FROM pictures p WHERE p.status = 'active' AND p.filename = :filename: LIMIT :limit: OFFSET :offset:";
    $pictures = $app->modelsManager->executeQuery($phql, array(
        "limit" => $limit,
        "offset" => $offset,
        'filename' => $filename
    ));

    $data = array();
    foreach ($pictures as $picture) {
        $data[] = array(
            'id' => $picture->id,
            'filename' => $picture->filename,
            'age' => $picture->age,
        );
    }

    echo json_encode($data);
});

the error
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''10' OFFSET '0'' at line 1' in /media/sf_pattegufv3/index.php:29 Stack trace: #0 [internal function]: PDOStatement->execute() #1 [internal function]: Phalcon\Db\Adapter\Pdo->executePrepared(Object(PDOStatement), Array, NULL) #2 [internal function]: Phalcon\Db\Adapter\Pdo->query('SELECT p.id...', Array, NULL) #3 [internal function]: Phalcon\Mvc\Model\Query->_executeSelect(Array, Array, NULL) #4 [internal function]: Phalcon\Mvc\Model\Query->execute(Array, NULL) #5 /media/sf_pattegufv3/index.php(29): Phalcon\Mvc\Model\Manager->executeQuery('SELECT p.id, p....', Array) #6 [internal function]: {closure}() #7 /media/sf_pattegufv3/index.php(58): Phalcon\Mvc\Micro->handle() #8 {main} thrown in /media/sf_pattegufv3/index.php on line 29

When i change :limit: and :offset: to the numbers up in my function() does it works like a charm.

don't mind the filename it was just to test if the problem was with a string too.
