(30) There was war . . .--Of such war we have no record, since the day when Shemaiah forbade Rehoboam's invasion of the new kingdom; nor is there even mention of any action of Israel in aid of the Egyptian attack, although it is likely enough that such action was taken. The meaning may simply be that there was continued enmity, breaking off all peaceful relations; but in the scantiness of the record we can have no certainty that actual war did not take place, though it has found no place in the history.

Verse 30. - And there was war [cf. 2 Chronicles 12:15, "wars." Keil argues from the prohibition of war by Shemaiah (1 Kings 12:23) that this must mean "hostility, enmity." But מִלְחָמָה surely implies more than angry feelings or a hostile attitude; and it is highly probable that, even if there were no organized campaigns, a desultory warfare was constantly carried on on the borders of the two kingdoms. It is also possible that Jeroboam took a part in the war of Shishak] between Rehoboam and Jeroboam all their days.

14:21-31 Here is no good said of Rehoboam, and much said to the disadvantage of his subjects. The abounding of the worst crimes, of the worst of the heathen, in Jerusalem, the city the Lord had chosen for his temple and his worship, shows that nothing can mend the hearts of fallen men but the sanctifying grace of the Holy Spirit. On this alone may we depend; for this let us daily pray, in behalf of ourselves and all around us. The splendour of their temple, the pomp of their priesthood, and all the advantages with which their religion was attended, could not prevail to keep them close to it; nothing less than the pouring out the Spirit will keep God's Israel in their allegiance to him. Sin exposes, makes poor, and weakens any people. Shishak, king of Egypt, came and took away the treasures. Sin makes the gold become dim, changes the most fine gold, and turns it into brass.And there was war between Rehoboam and Jeroboam all their days. For though Rehoboam did not enter into an offensive war, and attack the children of Israel, being dissuaded from it by Shemaiah the prophet in the name of the Lord, yet he might maintain a defensive war; and though there were no pitched battles between them as afterwards, in his son's time, yet there might be skirmishes and bickerings on the borders of their countries.
