There are two reasons why somebody would be kind, one out of greatness and power and wealth, where he has the feeling that he would like to share a little bit, there he takes most for himself and gives away a little bit, there is another kind of kindness which comes from humility, where he feels everybody else is entitled, so he takes a little bit for himself and gives away the rest even to somebody that’s very simple, and he’s willing to put himself in danger for that, that was the kindness of a Avrohom Avinu, therefore meriting the two Mitzvahs of the ashes of the Para Aduma and the dirt of the Sota, both representing kindness from humility. לקו״ש כה-ב
