C-14 Dating of Pharoah Shishak and King Solomon shows early date

1. Solomon sought therefore to put Jeroboam to death; but Jeroboam arose and fled to Egypt to Shishak king of Egypt, and he was in Egypt until the death of Solomon. (1 Kings 11:40)
2. Now it happened in the fifth year of King Rehoboam, that Shishak the king of Egypt came up against Jerusalem. He took away the treasures of the house of the LORD and the treasures of the king's house, and he took everything, even taking all the shields of gold which Solomon had made. (1 Kings 14:25-26)

"However, the discovery of pottery assemblages with biblical data relating to the monarchies of David and Solomon in the destruction layer of Jezreel, a royal citadel of the Omride Dynasty, which ruled over the northern Kingdom of Israel from 885 to 843 B.C., suggested that the older dates for key sites in Israel (e.g., Hazor, Megiddo, and Gezer) might be much later than the time of King Solomon (second half of the 10th century B.C.). The implication was that archaeological layers traditionally associated with the monarchies of David and Solomon were too young to fit the biblical claims."
 "¹⁴C radiocarbon dating placed the destruction of Tel Rehov at 940-900 B.C., instead of the later date suggested by the associated pottery."
"High-precision radiocarbon dating of Tel Rehov establishes a date earlier than that suggested by previous studies utilizing pottery finds. The accuracy of ¹⁴C dating calls into question previous studies based solely upon pottery evidence. The current dating of Tel Rehov confirms the biblical date for Shishak's invasion of Israel."
