In the famous phrase: חזק חזק ונתחזק
What exactly does the word נתחזק v’nitchazek/v’nitchazak mean?
I’ve seen different translations like: “may we be strenghtened” “ let us be strenghtened” “ les us strengthen one another (i.e. eachother)”
What does this word imply? And who does the strenghtening (we ourselves, another, HaShem)? Or by what are we strenghtened?
