והיה. הזכיר הכנעני לבדו כי הוא אב לכולם: AND IT SHALL BE. Moses mentions only the Canaanite, because he was the father of them all.38Gen. 10:15-18. Hence the term Canaanite includes all the inhabitants of Canaan. Also see I.E. on Gen. 15:20
וטעם נשבע ל. ך. כמו כי לך ולזרעך אתן את כל הארצות האל: [AS HE SWORE UNTO THEE.] Its meaning is similar to for unto thee, and unto thy seed, I will give this land (Gen. 26:3).39As He swore unto thee and to thy fathers means as He swore unto your fathers to give this land to you their seed (Krinsky), as we do not find God taking this oath to the generation enslaved in Egypt.
