The following article from Chabad.org claims that one should ‘offer one’s back / cheek’ to no one but Hashem:
This does seem to me to be a fair reading of Eicha 3:30, but it does not account for Yeshayahu 50:6-7, which specifically opposes the floggers, spitters and insulters to Hashem, Who upholds and protects the Navi in the face of these things.
It would therefore seem to me that ‘turning the other cheek’ is, in some circumstances, a Jewish value.
Have any recognised authorities endorsed this view, and, if so, have any said anything about whether one ought to solicit abuse and insult (or rebuke) in the case of an angry person (i.e. by asking them how one can improve)?
Thanks in advance.
