Die Söhne Josef sprachen: Das Gebirge wird für uns nicht ausreichen; und eiserne Wagen gibt es bei dem Kanaani, der im Tal-Lande wohnt, bei denen in Bet Seon und seinen Tochterstädten und denen im Tale Israel, [wir können ihn nicht besiegen].
Rashi on Joshua
The mountain will not be sufficient for us. For it is too crowded for us as you [just] said.
Rashi on Joshua
Iron chariots. ‘And that what you say, go up to the forest and conquer the land of the Perezzites and the Rephaim [is not so simple] because the Canaanites are a mighty people, and they possess iron chariots.’ Do not wonder if Scripture refers to the Perezzites and Rephaim as Canaanites for they were all descendants of the original Canaan.12The original Canaan was the grandson of Noach, who was cursed by Noach. See Bereishis 9:25.
