What does Ezra 9:3 mean?

When I heard about this, I tore my clothes and pulled out some of my hair and beard. I just sat there, completely shocked and devastated. Ezra 9:3 - Modern Text Bible

(Ezra reacts with deep grief and distress, showing how seriously he takes this situation. Tearing clothes and pulling hair were ways people showed intense sorrow or outrage in that culture.)
