"Ka'asher assah hayom hazeh tzivah Hashem la'asos l'chaper aleichem . (8:34)
Like He Did on This Day, so did Hashem command to do to atone on you."
The way to do teshuva is by concentrating that TODAY should be clean! One Day At A Time!
Ka'asher assah hayom hazeh - to concentrate on my performance TODAY. This is what Hashem wants us to do. This will be l'chaper aleichem - our kapparah !
