I sell a shirt in my merch, also a coffee cup that says, "Be Like Nachshon." What does this mean?

When the Jews had their backs to the Sea of Reeds and the Egyptian Army was coming upon them, the Jewish people were terrified and got into an argument over what to do. Surrender? Fight? No place to run? Moses started to pray. God told him it was not the time to pray. Nachshon, the prince of the tribe of Yehuda, the ancestor of King Dovid, just kept going. He walked into the sea. When he was up to his neck he cried out to God. That's when the sea split. The take home is to stay out of fear, anger, and the intellect, and just keep going. Not a time for fear or anger, a time to think with your heart and just keep going. BE LIKE NACHSHON!!!!
