וַיַּ֣עַל יְהוּדָ֔ה וַיִּתֵּ֧ן יְהוָ֛ה אֶת־הַכְּנַעֲנִ֥י וְהַפְּרִזִּ֖י בְּיָדָ֑ם וַיַּכּ֣וּם בְּבֶ֔זֶק עֲשֶׂ֥רֶת אֲלָפִ֖ים אִֽישׁ׃
猶大就上去，永恆者把迦南人和比利洗人交在他們手中，他們在比色擊殺了一萬人。
Sifrei Devarim
We are not told explicitly of the greatness of the Canaanites, but it may be readily inferred from the following (Judges 1:7) "And Adoni-bezek (a Canaanite king) said: 'Seventy kings, their thumbs and big toes cut off used to glean under my table.'" (Devarim, Ibid.) "And they (the descendants of Joseph) are the thousands of Ephraim, and they are the thousands of Menasheh": We are hereby taught that they were blessed with thousands and with ten thousands, viz. (Bamidbar 10:36) "the ten thousands thousands of Israel."
