[Aaron] said, "O son of my mother, do not seize [me] by my beard or by my head. Indeed, I feared that you would say, 'You caused division among the Children of Israel, and you did not observe [or await] my word.'"
When Moses took his brother by his beard and head, dragging him and scolding him for what he did, Aaron said to him, seeking his compassion: “Do not hold my beard and the hair on my head, for I have a reason for staying with them. I feared if I leave them alone they will disperse, then you will say I split them apart and that I did not maintain your bequest regarding them”.
