The holy faith of reformed samaritanism

He who refrains from rebuking a rebellious leader, will be forced to bear the same punishment 
«And the Lord spake unto Moses, saying, “Take the rod, and gather thou the assembly… 
speak ye unto the 
rock... and it shall give forth his water
… And Moses lifted up his hand, and with his rod 
he smote the rock 
twice
… And the Lord spake unto Moses and Aaron, 
Because ye believed me not,
to sanctify me in the eyes 
of the children of Israel, therefore 
ye shall not bring this congregation into the Land
which I have given 
them”- Numbers 20:7-8, &11-12 (King James Bible). 
Torah makes clear that Moses actually sinned (by hitting the Rock, instead of speaking unto it). But what was
Aaron’s guilt, that he should also be prevented from entering into the Land? According to Reformed 
Samaritanism, after Aaron saw Moses hitting the rock [for the first time], he should have confronted him 
[saying, “What are you doing? Didn’t God only ask you to speak unto it?”]. 
But, since Aaron remained silent, he was thereby guilty of publicly violating the Divine injunction that goes 
on to say: “
Thou shalt not hate thy brother
in thy heart; 
thou shalt surely rebuke thy neighbour, and not 
bear sin because of him
(in other words, not rebuking your brother’s rebellion isn’t only sinful, but also 
intimates you don’t really love him!)”- Leviticus 19:17 (Jewish Publication Society Bible, 1917 Edition). 
And the former truth is also asserted by the Jewish Scripture that goes on to say: “The Lord will enter 
into 
judgment with the elders of His people
, and the princes thereof ...”- Isaiah 3:14. Granted that the princes (the
rich and powerful) sinned; but why would the elders be also judged (being punished)? Because they saw the 
public sin of the princess, and decided to remain silent.
