A genealogy often serves as more than a simple family tree; it acts as a historical map. The lineage of Canaan defines the identity of the land's early inhabitants and outlines the borders of the inheritance destined for the Israelites. Unlike Canaan's brother Put, whose descendants remained a single unified nation and are therefore unlisted, Canaan's family expanded and fractured into many distinct groups that filled the region [רשב״ם, רד״ק].
God granted this territory to Canaan during the global dispersion of nations with a profound underlying purpose. Because Canaan carried the curse of servitude, he was legally incapable of true ownership, as any property acquired by a slave belongs entirely to his master. Therefore, Canaan received the land merely as a temporary deposit. He functioned as a caretaker, guarding God's estate until the Israelites would multiply and arrive to claim their rightful inheritance [רמב״ן, הטור הארוך, רבנו בחיי, תולדות יצחק].
While eleven sons of Canaan are recorded, this number presents a historical puzzle. Later on, God promises Abraham the territory of ten nations, and by the time of Moses and Joshua, only seven nations are mentioned. To resolve this, one approach suggests that the eleven sons eventually divided into twelve nations, perfectly mirroring the twelve tribes of Israel who would replace them. When Moses later lists only seven nations, he highlights the six most powerful groups and bundles the remaining smaller factions under the broad title of Canaanites [בכור שור, חזקוני]. Another perspective explains that the initial list records the sons' birth names. As these families migrated and settled, they adopted new identities based on their geographic locations or prominent tribal leaders, resulting in completely different names by the time of Abraham [רמב״ן, הטור הארוך, רבנו בחיי, תולדות יצחק].
Among the sons, Sidon holds a unique distinction as the firstborn. This title indicates that he surpassed his brothers not only in age but in overall status and influence [רד״ק]. Sidon represents the famous coastal city, and his birthright reflects the city's central role as a founding mother to other colonies in the region [קאסוטו, ביאור יש״ר]. Alternatively, because of his senior position, Sidon may have absorbed a weaker brother who never grew into a distinct nation, with both groups merging under the general identity of Canaanites [רמב״ן, רבנו בחיי, הטור הארוך, ביאור יש״ר].
Alongside Sidon is Heth, another foundational tribe that settled within the land. This group does not represent the massive Hittite empire of antiquity, but rather localized communities established within the regional borders. These are the same local inhabitants of Hebron whom Abraham would eventually encounter [שד״ל, קאסוטו, ביאור שטיינזלץ].
