As Kaiser says, "Thus, while the Sphinx Stele cannot be taken as direct proof of the death of the firstborn, enough evidence has been brought to light by Egyptologists to support the early date of the Exodus and the fact that indeed Thutmose IV had not expected to succeed his father to the throne."
Kwa mujibu wa Kaiser, "Hivyo, ingawa Sphinx Stele haiwezi kuchukuliwa kuwa ni kithibitishoo cha moja kwa moja cha mzaliwa wa kwanza, ushahidi wa kutosha umetolewa na wataalamu wa mambo ya Misri wenye kuthibitisha tarehe ya mapema (karne ya 15 KK) ya kutoka utmwani wa Misri kwa Waisraeli na ukweli kwamba Thutmose IV hakurithi kiti cha enzi cha baba yake."
