So Miriam was shut outside the camp seven days, and the people did not set out on the march till Miriam was brought in again.
Numbers 12:15 ESV

The people had great affection for all three of Amram's children. None-the-less, Torah doesn't hide family dirt. In fact, it often highlights the flaws of its "protagonists" so that God can use them to show us what not to do.
