[Avodah] TWO COMPELLING QUESTIONS

[Richard Wolberg]

In Pinchas 27:18 it states: ''...v'samachta es yadcha..." (lean your hand [singular]). 
Five p'sukim later 27:23 it states: ''Vayismoch es yadav alav...'' (He leaned his hands [plural]). 
And the pasuk immediately preceding (vs.22) states ''Vayaas Moshe kaasher tziva HaSem oso...'' 
How could it say that he did as he was commanded? He was commanded to lean ONE hand and 
he leaned TWO hands. Such a big deal is made out of his striking the rock instead of speaking to it, 
so how come he wasn't penalized for following the exact instructions (laying ONE instead of TWO
hands) and how could the Torah state that he did as HaShem commanded him?

Regarding speaking to the rock, the Torah commands Moshe to gather the eidah 
and Aharon and speak to the rock so that it will give its waters. First, the Torah 
doesn't tell him WHAT to say and the commandment is ''v'dibartem'' which is the
plural. Logistically, how were they all to speak together when they weren't even 
told what to say? Perhaps, Moshe was so overwhelmed not knowing what to say
or how they could all speak together that his frustration led him to strike the rock. 
(B'midbar 20:8).
