The White House today posted a Statement from President Biden (full text) sending best wishes for Yom Kippur to Jewish communities in the United States, Israel and around the world. The Statement says in part:
The blessing of Yom Kippur is that it is not just a day of reflection, repentance, and reverence – but a day of transformation, forgiveness, and hope. God invites us to write a new chapter in the story of our lives, and in the life of our nation. As the High Holidays conclude, let us all summon the courage to make the changes required to bridge the gap between the world we see and the world we seek.
Yom Kippur begins at sundown this evening.
