The Reach of a Voice Outruns the Grasp of a Hand

Yalkut Shimoni on Torah 115:6

"The voice is the voice of Jacob" (Genesis 27:22). Your strength is harder [greater] than that of Esau. Esau, if he seizes a man, behold he is in his hand; but if the man flees, he can do nothing to him. But you - even if a man flees to the end of the world, the voice you raise in the synagogue, behold it comes of itself [it reaches and is heard].
