This is a true story involving the Chofetz Chaim (1838-1933) and Rav Shimon Schwab (1908-1995).
Schwab once visited the Chofetz Chaim, and the Chofetz Chaim asked him
if he were a Kohen, Levi or Yisroel. Rav Schwab answered that he was a
Yisroel. As it is well known, the Chofetz Chaim was a Kohen [Priest,
descended from Aharon the High Priest].
The Chofetz Chaim said to
Rav Schwab, "Do you know the difference between me and you? Soon the
Beis HaMikdash [House of Sanctity - Temple] will be rebuilt. Everyone
will go crowd into the Courtyard of the Beis HaMikdash for the first
time. There will be a guard at the door who will ask the people whether
they are Kohanim, Leviim [Jews descended from the tribe of Levi], or
Yisraelim [Jews from tribes other than Levi]. The Kohanim will get to go
inside and do the Service of the Beis HaMikdash. I will be one of those
people. You, Rav Schwab, with all the other Yisraelim will be left
outside. All the Yisraelim will be terribly jealous of me. They are
going to want to do the Service, but the Halacha will be NO! -- Kohanim
inside; Yisraelim outside."
The Chofetz Chaim continued, "Do you
know why it will be like that? Because of something that happened
thousands of years ago. Thousands of years ago, there was an incident
called 'the sin of the Golden Calf.' The Jewish people sinned with the
calf. Only 3,000 people participated in that heinous act of idolatry.
But when Moshe Rabbeinu called out and asked everyone else to come and
put out the fire... When he issued those famous words 'Whoever is for
G-d, gather around me' [Shmos 32:26], do you know what happened? Only
the tribe of Levi showed up. My grandfather came and responded to that
call and your grandfather sat there and did nothing. Therefore, the
Kohanim, who come from the tribe of Levi, will go into the Beis
HaMikdash. But you, Yisraelim are going to be on the outside because you
sat there and did not respond."
The Chofetz Chaim then looked at
Rav Schwab and said to him, "What do you think? Am I trying to make you
feel bad? Am I trying to rub your face in it? Chas V'Sholom [Heaven
forbid]! I want to teach you a lesson. Many times in life, you will hear
a little voice go off in your head that will say 'Whoever is for G-d,
gather around me.' An event will occur or an issue will be raised.
Everybody is going to be told 'Stand up and be counted.' In whose camp
are you? I want you to know that questions like that and challenges like
that have implications not only for you but for generations and
generations after you. Because your grandfather did not answer 'Yes' in
the affirmative to 'Who is for G-d, gather to me', you are excluded from
the Beis HaMikdash Service. It was an act that has implications
thousands of years later. Because my grandfather said yes, I am a Kohen
now and I am going to do the Service."
"Never forget", the Chofetz
Chaim told Rav Schwab, "everybody has his moments of 'Who is for G-d,
gather around me.' When you hear that voice, stand up and be counted!”
