1 Kings 11:40

Solomon sought therefore to kill Jeroboam How Solomon came to know what was secretly transacted between Ahijah and Jeroboam alone, is a great question: perhaps the prophet made no scruple to report what he had delivered in the name of the Lord. Or, Jeroboam himself, being puffed up with the expectation of ascending the throne, could not conceal it, nor keep his own counsel, but told the matter to some of his confidants, who spread it abroad. But that Solomon should ever entertain a thought of endeavouring to defeat the purpose of God, is astonishing indeed! Jeroboam arose and fled unto Shishak king of Egypt Solomon's brother-in-law, as is probable, who yet might be jealous of him, or alienated from him, because he had taken so many other wives to his sister; or might cast a greedy eye upon the great riches which Solomon had amassed together, and upon which, presently after Solomon's death, he laid violent hands, 2 Chronicles 12:9. We may observe here that all the kings of Egypt, from the time of Abraham, are in the sacred history called by the name of Pharaoh, unless Rameses (mentioned Genesis 47.) be the name of a king, not of a country; so that this is the first we meet with called by his proper name, different from the rest of the Pharaohs. The opinion is pretty general that this was the great king, called by the Greeks Sesostris, who, having subdued Ethiopia, extended his conquests into Asia, as far as the Assyrians and Medes, as Josephus tells us, who calls him Sethosis.
