Rashi on Genesis 37:17/רש"י על בראשית ל״ז:י״ז

1נסעו מזה THEY HAVE JOURNEYED HENCE — they have departed from all feeling of brotherhood.

2נלכה דתינה LET US GO TO DOTHAN — “let us go to seek some legal (דתות) pretexts” to put you to death. According to the literal sense, however, it is the name of place, and Scripture never really loses its literal sense (Shabbat 63a).
