conditional multi-lingual laravel seeder

Suppose i have a table that contains a set of data in multiple languages and a foreign key lang_code referencing to the code on language table.

now i have to seed data table based on lang_code (en, es). How do i make conditional seeder to seed based upon the foreign key value being assigned, i.e. if the lang_code id en then seed in english and so on.

here is what i have on the dataTableSeeder

public function run(Faker $faker)
{
    $fakerEs = Faker\Factory::create('es_ES');
    $instructionIDs = DB::table('oes_instructions')->pluck('id')->toArray();;
    $languageIDs = DB::table('oes_languages')->pluck('code')->toArray();;

    foreach (range(1,4) as $index) {
        DB::table('oes_exam_instructions_data')->insert([
        'instruction_id' => $faker->randomElement($instructionIDs),
        'locale' => $faker->randomElement($languageIDs), 
        'content' => $faker->paragraphs(10, $asText = true),   
        //Here ho do i make this based on $languageIDs => $faker->paragraphs(10, $asText = true) 
        'created_at' => Carbon::now()->format('Y-m-d H:i:s'),
        'updated_at' => Carbon::now()->format('Y-m-d H:i:s')
        ]);
    }
}
