1 Kings 11:40

Solomon sought therefore to kill Jeroboam. And Jeroboam arose, and fled into Egypt, unto Shishak king of Egypt, and was in Egypt until the death of Solomon.

Shishak - or Shishonk, according to the Egyptian monuments, who harboured and encouraged the rebellious refugee, was of a different dynasty from the father-in-law of Solomon. The dynasty of the military pontiffs had just terminated, and was succeeded by the 22nd dynasty, of which Shishak was the founder.
