The first mention of Israel is in the Victory Stela of Merneptah, the Egyptian Pharaoh, erected ca. 1210 BCE.
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, Merenptah, Content with Maat,
Given life like Re every day.
Israel is mentioned with other countries lying to the northeast of Egypt. The determinative is that for people, so it was not a country at the time.
