What is "Masa ba'Rav"?
Rashi: It is a Nevu'ah about Aravim.
Radak: It is about Arav, Bnei Kedar 1 (Malbim - they fell to Sancheriv). The prefix Beis in ba'Rav is in place of Al, like "Ken Yinasen Bo 2 " (Vayikra 24:20), "ha'Behemah Asher Ani Rochev Bah" (Nechemyah 2:12).
Kedar was a son of Yishmael (Bereishis 25:13). Below (16-17) it mentions Bnei Kedar. (PF)
Ibn Ezra (Shemos 21:24, Perush ha'Aruch, citing Rav Sadya Gaon): We do not wound one who wounded. Rather, Ken Yinasen Alav Onesh; Bo is in place of Al.
What is the meaning of "ba'Ya'ar Barav Talinu"?
Targum Yonasan: They will lodge at night in the forest. Radak - he explains Barav like ba'Erev.
Rashi: I saw what you did in Galus Ashur 1 to My nation. Yisrael asked their captors to lead them by you, for you are their cousins - perhaps you will have mercy on them, and you went out and lodged in the forest, in the place where caravans pass. (Refer to 21:14:1:2).
I.e. of the 10 tribes. Rashi (14) says that the Aravim killed them via inflated pouches. Eichah Rabah (2) expounds so regarding Galus Bavel. Why did Rashi say that this refers to Galus Ashur? (PF)
What are "Orchos Dodanim"?
Rashi: The sons of Dodeichen 1 (your uncles).
Radak, Malbim: This refers to caravans of Bnei Dedan 2 , which used to pass in Arav. Now that Arav was destroyed, you will lodge in the forests, for you will not find tents to lodge in, for the tents of Kedar were destroyed. Malbim - Bnei Kedar used to host guests. Aravim do so also nowadays.
Kli Paz cites Rashi to say Dodeichem.
We find that a grandson of Kush was named Dedan, and also a grandson of Keturah (Bereishis 10:7, 25:3). Surely Radak refers to the latter. (PF)
