MeAm Lo'ez on Yeshayahu 41:10

So fear not, Jewish people, says G-d, for I have strengthened you in the past with encouraging words and helped you in days gone by.  Let not the long exile make you fainthearted, for I am with you throughout it to support you.  I shall strengthen you and help you against the onslaught of the nations so that they be unable to separate you from Me, your g-d.  Fear not those nations among which you dwell, as Avraham feared not those mighty kings.
