“And you shall be clear before the Lord and before Israel” (Numbers
32:22). 

Meaning that we can say God knows what I’m all about and do things that
look wrong. We have to do the right thing in the eyes of the people. 

But what about a case where I have a constant critic. Do I have to adjust
my life for that person? And it seems not because Moses does his debts best
with Datan but everyone knows that no matter what he does Datan is going to
criticize him. 

G-d called Moshe 'trustworthy' (Bamidbar 12:7). Why then did
Moshe need to make a public accounting in front of all the people? 

Moshe had overheard remarks such as 'Ben Amram’s (Moshe’s) neck is
getting pretty fat lately.' 'No wonder. He’s in charge of all that
money for the Mishkan!' 

Certainly, these remarks were only made by lowlifes. The Jewish People as
a whole trusted Moshe but they were puzzled about Moshe’s sudden wealth. They
didn’t know that G-d had let Moshe keep the fragments of sapphire left over
from the hewing of the second Tablets. These splinters of sapphire made Moshe
extremely wealthy. 

Moshe was scrupulous to a ‘T’ with the donations he received for the
Mishkan, but nevertheless he gave an accounting because he didn’t want to be
suspected falsely of doing a little laundering on the side. 

From Moshe, our Teacher, we can learn that it’s not enough for us to do
the right thing, but we must also be seen to do the right thing.
