In the final scene of "Fiddler On The Roof" - the Anatevkans are gathered as they mourn the necessity to depart their cherished town.
As is true to form with the dark comedic format this tragic story tells, the town's spiritual leader (No name given other than "Our Beloved Rabbi") remarks: "Our forefathers have been forced out of many, many places at a moment's notice." Tevye has a typical dichotomous simple/profound response: "Maybe that's why we always wear our hats."
As we face the Abrahamic dilemma of "going to a place we do not know" we trust and take comfort in God's promises. They are not mere poetry - rather revelation to rely on with a proven track record for multiple generations of followers.
Among the promises are the words found in Isaiah 45:2 &3
I will go before you
and will level the mountains;
I will break down gates of bronze
and cut through bars of iron.
I will give you the treasures of darkness,
riches stored in secret places,
so that you may know that I am the LORD,
the God of Israel, who summons you by name.
