Thayer, as opposed to Trench and others, would make the distinction
between these two words to be this: ``aitew signifies to ask for
something to be given, not done, giving prominence to the thing asked
for rather than the person, and hence is rarely used in exhortation.
erwtaw, on the other hand, is to request a person to do (rarely to
give) something; referring more directly to the person, it is naturally
used in exhortation, etc.''
