What are the implications of "Vekashlu Ish be'Achiv"?
Rashi #1, Targum Onkelos and Targum Yonasan: It implies that, in their haste to escape from the enemy, they will stumble over each other
Rashi #2: Refer to 26:37:2:2.
Why does the Torah insert the 'Kaf' in the word "ke'Mipnei Cherev"?
Rashi #1, Targum Onkelos and Targum Yonasan: To teach us that they will flee in terror as if they were being chased by the sword, when in fact, there is nobody running after them.
Rashi #2: With reference to "Vekashlu Ish be'Achiv", and based on the principle 'All of Yisrael are responsible for one another', it means that one man will stumble over another's sins 1 - just as a man stumbles before the sword that is pursuing after him.
R. Bachye: Like we find by Achan, where many were punished because he sinned, as the Navi writes in Yehoshua 7:11. See also R. Bachye citing Shir Hashirim Rabah.
