And they wept
(Gen 33:4)
What is the sound of men weeping? In several cultures the weeping man is unacceptable. So the weeping man is an unknown sound and when the sound comes up it seems inhuman and alien.
But why do Jacob and Esau weep? It is unclear and the sounds of the text leave us guessing. Esau without pronouncing the sound of forgiveness seems to have forgiven Jacob. This without Jacob pronouncing the sound of apology.
