And in the fifth year of the reign of Roboam, Sesac king of Egypt came up against Jerusalem.

And it came to pass in the fifth year of king Rehoboam, that Shishak king of Egypt came up against Jerusalem: o

And it cometh to pass, in the fifth year of king Rehoboam, gone up hath Shishak king of Egypt against Jerusalem,

Then, in the fifth year of the reign of Rehoboam, Shishak, the king of Egypt, ascended against Jerusalem.

The examination of the famous inscription of Shishak at Karnak has resulted in the proof that the expedition commemorated was directed against Palestine, and has further thrown a good deal of light on the relations of the two kingdoms at the period. Of the fifteen fenced cities fortified by Rehoboam in the early part of his reign 2-Chronicles 11:5-12, three, Shoco, Adoraim, and Aijalon are distinctly mentioned among Shishak's conquests. Other towns of Judah or Benjamin also occur. Further, a considerable number of the captured cities are in the territory of Jeroboam: these cities "are either Canaanite or Levitical." Hence, we gather, that, during the four years which immediately followed the separation of the kingdoms, Rehoboam retained a powerful hold on the dominions of his rival, many Canaanite and Levitical towns acknowledging his sovereignty, and maintaining themselves against Jeroboam, who probably called in Shishak mainly to assist him in compelling these cities to submission. The campaign was completely successful.

And it came to pass in the fifth year of King Rehoboam,.... Two years after he and his people fell into the above wicked practices:
that Shishak, king of Egypt came up against Jerusalem; of whom see 1-Kings 11:40, this was suffered as a chastisement from the Lord for their abominations.

SHISHAK SPOILS JERUSALEM. (1-Kings 14:25-31)
Shishak king of Egypt came up--He was the instrument in the hand of Providence for punishing the national defection. Even though this king had been Solomon's father-in-law, he was no relation of Rehoboam's; but there is a strong probability that he belonged to another dynasty (see on 2-Chronicles 12:2). He was the Sheshonk of the Egyptian monuments, who is depicted on a bas-relief at Karnak, as dragging captives, who, from their peculiar physiognomy, are universally admitted to be Jews.

Fifth year - Presently after his and his people's apostacy, which was not 'till his fourth year: while apostate, Israel enjoyed peace and some kind of prosperity, of which difference, two reasons may be given: first, Judah's sins were committed against clearer light, and more powerful means and remedies of all sorts, and therefore deserved more severe and speedy judgments. Secondly, God discovered more love to Judah in chastizing them speedily, that they might be humbled, reformed, and preserved, as it happened; and more anger against Israel, whom he spared to that total destruction which he intended to bring upon them. Sishak - He is thought to be Solomon's brother - in - law. But how little such relations signify among princes, when their interest is concerned, all histories witness. Besides Rehoboam was not Solomon's son by Pharaoh's daughter and so the relation was in a manner extinct. Came up - Either, from a desire to enlarge his empire: or, by Jeroboam's instigation: or from a covetous desire of possessing those great treasures which David and Solomon had left: and above all, by God's providence, disposing his heart to this expedition for Rehoboam's punishment.
