13 Preface وَيَضيقُ صَدري وَلا يَنطَلِقُ لِساني فَأَرسِل إِلىٰ هارونَYusuf Ali“My breast will be straitened.1 And my speech may not go (smoothly): so send unto Aaron.As we should say in English, “My heart would fail me, and my tongue cleave to my mouth.” Moses had an impediment of speech, and his mission was risky: see next note. But God’s Plan works in wondrous ways. Aaron was given to assist him in his mission, and Moses’s shortcomings were transformed by God’s grace into power, so that he became the most powerful leader of Israel.
