Moses did so...
THE COMMENTARY THE CONSIDERED REQUESTS OF MOSES VERSE NO.24ِ36 At last Moses was chosen a prophet by his Lord, Allah, (YAHOVAH), and was spiritually prepared to attend his commission, but he knew enough of Pharaoh, and that how unrestrained and immoderate the tyrant was. He therefore prayed to our Lord for some means of confronting with the dictator of Egypt. First of all he prayed to Allah to grant him more spiritual insight, by the expansion of his breast, which we may take it as a broad mind.
He asked for God's help in removing the hardship and difficulties of his mission and tasks. He also asked for the power of eloquence and the removal of any impediment from his speech. Some commentators have narrated that the tongue of Moses had [ 99 ] been burned when he was a child, and the verse (NO.27) has been sent down to this effect that:ِ ``My Lord!
Loosen the knot from my tongue.'' But the next verse (NO.28), implies that he has prayed for eloquence, so as to be able to express his feelings, or what was inspired to him with a more moving force and fluency:ِ ``That they may easily understand what I say to them.'' In the next verse (NO.29) Moses prays to his Lord to assign his brother, Aaron, as his VAZIR, or a minister by our translation. The Arabic, ``VAZIR'' is taken from the root word, ``VEZR'' which means a heavy load.
