يعض اليد التي تطعمه, ينكر الجميل

to harm someone who is helping you or providing for you

:
He shouldn't bite the hand that feeds him by criticizing his boss publicly.
لا ينبغي له أن يعض اليد التي تطعمه بانتقاد رئيسه علناً.
After all the help they gave him, it was shocking to see him bite the hand that feeds him.
بعد كل المساعدة التي قدموها له، كان من الصادم رؤيته يعض اليد التي تطعمه.
