The Robbers and the Tefillin
When thieves attacked his wagon, the Shaagas Aryeh looked out in his tefillin, and the robbers ran.
It is told that the Shaagas Aryeh was once riding in a covered wagon along a lonely road. He sat wrapped in his tallis, tefillin on his head, absorbed in his learning, when a gang of robbers stopped the wagon and began to threaten the driver for his money.
Hearing the shouting, the Rav understood what was happening. He leaned out to see for himself. The moment the men looked up and met his face, shining and still beneath the tefillin, they were seized with terror. They dropped what they were doing and ran off as if pursued.
The driver could hardly believe it. He asked the Rav what had frightened the men so badly. The Shaagas Aryeh answered with a verse. The Torah promises that every nation will see Hashem's name proclaimed over Israel, and will stand in awe of them. Our Sages teach that this refers to the tefillin on a Jew's head. That was what the robbers had seen, he explained, and it was enough to send them running.
Then he returned to his sefer, and the wagon went on its way.

The Rav did nothing but be himself, wrapped in his tallis and tefillin, and that was protection enough. Most of us carry something visible of who we are, whether a kippah, a way of speaking, or the care we show others. Today, notice one moment when you could act as someone who belongs to Hashem: pause before replying sharply, say a bracha aloud, or put on your tefillin slowly and with attention. Let the calm of that moment be the message.
