Protecting another's dignity at any cost

Rachel gave Leah the secret signs she had arranged with Yaakov, so that her sister would not be humiliated on her wedding night. She risked losing the husband she had waited seven years for, and she did it in silence, without seeking credit. Chazal teach that because of this hidden modesty she merited that Shaul HaMelech, himself known for his modesty, would descend from her. True greatness is often invisible, measured by what a person quietly gives up for another.
