"And my breast will be constricted (so that I fail to show the necessary perseverance and tolerance), and my tongue will not be free (to convey Your Message with the right fluency), so appoint Aaron as a Messenger beside me
And my breast will be straitened, and my tongue will not be free. (i.e., it will not express well; literally, will not go off freely) So send to Harun. (Aaron)
“I may loose my temper. Besides, I have a problem with my tongue (and I cannot deliver an effective speech.) Would you kindly appoint my brother Aaron as my assistant.&rdquo
Faridul Haque
“I feel hesitant, and my tongue does not speak fast, therefore make Haroon also a Noble Messenger.&rdquo
Hasan Al-Fatih Qaribullah
and my chest will become constricted and my tongue will not be loosed (in my speech), therefore, send to Aaron
`And my bosom straitens, (and my heart fails me), and my tongue is not fluent (for feeling inadequate to deliver the message I am entrusted with), therefore send to Aaron (to help me)
And my breast constricts (under such adverse circumstances) and my tongue does not express (fluently), so send (Gabriel with revelation) to Harun ([Aaron] as well so that he becomes my helper)
“I feel constricted and tongue-tied, so appoint Aaron (for this task instead)!”
Sayyed Abbas Sadr-Ameli
And my breast straitens, and my tongue is not eloquent, therefore sent for Aaron (to help me)
Al-muntakhab fi tafsir al-Qur'an al-Karim
"And my chest becomes drawn tight and my mind and my feeling become strained and my tongue becomes restrained from free expression, therefore I pray and beseech You O Allah, my Creator, to send -The Angel Gabriel- to my brother Harun"
