פירוש על ויקרא 26:23

‎‏ לא תוסרו לי‏AND IF YOU WILL NOT BE CHASTISED — so that you should return unto Me.

To return to Me. Because the expression לא תוסרו לי (lit. do not accept your sufferings) is problematical, as people obviously do not want to accept sufferings [and they sufferings are given to people whether they want them or not]. Therefore Rashi explains: If, despite all these sufferings, you do not want to return to Me.
