It is the absence of a hebrew word for 'side' plus the fact that this
is even inserted in ex 17 since one would assume naturally that the
reader could easily have understood that chur and Aharon would not
have both stood on one side of Moshe, it seems honestly to be a
redundant extra piece of information - a tautology really considering
the previous verse, but it's there and there for a reason. I
understand that a double use of the word 'echad' in proximity can
mean 'one another' or 'each other'. Is this construction in Ex 17
unusual?
