Earlier in the semester, we talked about the word “Hineni” used by figures in the Hebrew Bible to say “Here I am”. There are two ways to say “I’m here” in Hebrew. The first is “poh”. This would be used as a response to a roll call, or just a general “I’m here at the store.” The second way to say that you here is “Hineni” this word has a more complete, deeper meaning.
