The phrase that is translated in English translations as “are horrified and shake their heads” is translated into Afar as Ahamal qagabsiteloonuuh, namma xabanal gaba hayya heenih.: “They are shocked at this, and put both hands on their cheeks.” (Shock is expressed physically by placing their hands on their cheeks, not shaking their heads.)
