Constraining relationship query by an array

I have 3 models Content, ContentType, and Taxonomy. Their relationships are set up like this:

Content model:

public function contentType()
{
    return $this->belongsTo('App\ContentType', 'ct_id');
}
public function taxonomies()
{
    return $this->morphToMany('App\Taxonomy', 'taxonomical');
}

ContentType model:

public function contents()
{
    return $this->hasMany('App\Content', 'ct_id', 'id');
}

Taxonomy:

public function contents()
{
    return $this->morphedByMany('App\Content', 'taxonomical');
}

I am getting an array with taxonomies that I should use to filter the contents, the array could look like this one:

$taxonomiesArray =  ["Administrasjon", "Oslo", "Bane"]

With this kind of array I should make a query, where I would get only contents, that have all the taxonomies from that array, and are of contentType where column name is intranet-post, basically something like this:

$intranetTypePostID = ContentType::where('name', 'intranet-post')->pluck('id');
$contents = Content::where('ct_id', $intranetTypePostID)->with('taxonomies')->get();

But, how can I get only contents that have all the taxonomies that have the same name as the values from the array $taxonomiesArray?
