Commentaire sur La Genèse 37:17

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

THEY HAVE JOURNEYED HENCE. “They have departed from any feeling of brotherhood. ‘Let us go to Dothan, that is, let us go to seek pretexts of dathoth (laws) with which to put you to death.’ According to the literal sense, however, Dothan is the name of a place, and Scripture never sheds its literal sense.” This is Rabbi Shlomo’s [Rashi’s] language.
Now it was not the intent of our Rabbis to say that the man expressly told him, “They have departed hence from any feeling of brotherhood, and they have gone to stir up charges and pretexts against you,” for if so, he would have avoided going there and would not have endangered himself. Instead, their intent is to say that “the man” — Gabriel⁶¹So identified in Rashi (Verse 15), and the source thereof is Pirkei d’Rabbi Eliezer, Chapter 38. — who told it to him told the truth, but he spoke words having a double meaning, both of them true. Joseph, however, did not grasp the hidden meaning therein, and he followed the obvious. He thus followed his brothers and found them in Dothan, as he had told him. The Rabbis expounded this on the basis of the fact that the “man” referred to was an angel, and if so, he knew where the brothers were. Why then did he not say, “They are in Dothan,” instead of speaking as if he was in doubt, i.e., that he heard from them that they were going to Dothan but he does not know where they are at present. It is for this reason that they expounded the above Midrash concerning his words.

בדותן, according to the plain meaning this was the name of a town, and the town is also mentioned in the Book of Kings II 6,13.
