"piousness" - Translation from English to Arabic

Under all that piousness and fidelity... there's a real darkness.
خلف كل ذلك التظاهر ...بالتدين والأخلاص هناك ظلام حقيقي

'Twas a veiled manifestation of his piousness.
خدعة منه ليظهر ورعه.

They mock our humility and our piousness.
يسخرون من تواضعنا وتقوانا
