This translation rearranges the phrases of the original Hebrew. That is necessary for better understanding in English. A more literal translation might be: "among all the nations where (God) has banished you, the Eternal your God is there; you shall return to the Eternal your God."
This is the way the Chasidic teacher Mordechai of Neschiz (1752-1800) read it. And here is what he has to say about it: "This is in defence of Israel who have been banished to places where, if the angels had been scattered in as many places, they too would have become sinners. 'Where[-ever God] has banished you', nevertheless, 'the Eternal your God is there.'"
Life is hard. We all must face its challenges: making a living, looking after ourselves and our families, negotiating a host of relationships from the most intimate to finding our way through the crowds on the tube or the bus. We are constantly faced with decisions, great and small. Life is stressful; nothing is certain, except that one day we will die.
Under circumstances like these, is it any wonder that we sometimes get things wrong, or even deliberately try to manipulate things to our own advantage and the disadvantage of others? The Neschizer Rebbe says even angels would have been hard-pressed to avoid sinning, had they been faced with what we have to confront every day.
