The princes are prostrate saying: "Shalom!"
Not one of the Nine Bows lifts his head:
Tjehenu is vanquished, Khatti at peace,
Canaan is captive with all woe.
Ashkelon is conquered, Gezer seized,
Yanoam made nonexistent;
Israel is wasted, bare of seed,
Khor is become a widow for Egypt.
All who roamed have been subdued.
By the King of Upper and Lower Egypt, Banere-meramun,
Son of Re, Merneptah, Content with Maat,
Given life like Re every day.
Stories evolve. It is likely that stories of victory over Canaanite tribes evolved and merged over generations of oral transmission, eventually become relatively stable elements of the people's folklore, folk history. Some were allowed to drift. Some were retroactively imbued with religious (or new etiological) import. The
'genocide' was not the story but, rather, the context. Rendering one's enemy
"nonexistent, ... wasted, bare of seed" was simply the accepted bombast of the day. The story was all about
why it was done, and the
whys are laced with transcendent themes.
God is injected into national[istic] lore in an effort to sanctify the profane, to transmute lore into lesson. The effort was uneven and never free of perspective. The Priests had an agenda, as did the Deuteronomists. Postexilic redactors faced a Levant much different from the one they left. One can easily step through the Tanakh and find much to ridicule. Or one can see the aggregate as the evolving narrative of a people seeking to understand what a covenant with holiness entails. One can childishly complain about God destroying Sodom and Gomorrah, or one can embrace a theology that applauds the 'fact' that Abraham argued with God ...
... or one can contemptuously ask: "why waste effort studying a made up book?"
