Biblical Hebrew is a finely nuanced language, and much is expressed by the choice of words. 

After Adam and Eve eat from the Tree of Knowledge of Good and Evil in the Garden of Eden, in violation of the only commandment G-d had given them, they hear G-d’s presence in the Garden and hide from Him.  G-d calls out to the man (collectively including Adam and Eve), and says, “Where are you?”  (Genesis 3:8-9).

Many have mocked this question.  Doesn’t the omniscient G-d know where Adam is?  The common explanation is that G-d wanted to give an opening to Adam to tell God what he had done and to repent, but Adam does not take that opening, leading to expulsion from the Garden.

But there is a deeper meaning.  The word used in the verse to ask “Where are you?” is ‘ayeka’.  There are several words in Hebrew that mean ‘where’.  The word chosen here has a more specific meaning, as described by Nehama Leibowitz and other scholars. This word means not so much ‘where’, but ‘why aren’t you here?’  G-d was saying why are you not with Me, why are you distancing yourself for a relationship with Me?

Rosh Hashana represents the creation of the world and more specifically the creation of man.  And the question of ‘Ayeka’, applies to each of us.  Where are you? Why are you not facing up to a relationship with G-d and to your purpose and the contribution you can uniquely make to the world? One goal of Rosh Hashana is to help us regain this relationship and to focus on who we are and what we should be doing in this world.
