I Kings 12:13

II. History of the Kingdoms of Israel and Judah to the Destruction of the Former - 1 Kings 12-2 Kings 17 After the death of Solomon the Israelitish kingdom of God was rent asunder, through the renunciation of the Davidic sovereignty by the ten tribes, into the two kingdoms of Israel (the ten tribes) and Judah; and through this division not only was the external political power of the Israelitish state weakened, but the internal spiritual power of the covenant nation was deeply shaken. And whilst the division itself gave rise to two small and weak kingdoms in the place of one strong nation, the power of both was still further shaken by their attitude towards each other. - The history of the two kingdoms divides itself into three epochs. In the first epoch, i.e., the period from Jeroboam to Omri in Israel, and from Rehoboam to Asa in Judah (1 Kings 12-16), they maintained a hostile attitude towards each other, until Israel sustained a severe defeat in a great war with Judah; and on the renewal of its attacks upon Judah, king Asa called the Syrians to his help, and thereby entangled Israel in long and severe conflicts with this powerful neighbouring state. The hostility terminated in the second epoch, under Ahab and his sons Ahaziah and Joram in Israel, and under Jehoshaphat, Joram, and Ahaziah of Judah, since the two royal families connected themselves by marriage, and formed an alliance for the purpose of a joint attack upon their foreign foes, until the kings of both kingdoms, viz., Joram of Israel and Ahaziah of Judah, were slain at the same time by Jehu (1 Kings 17-2 Kings 10:27). This period of union was followed in the third epoch, from Jehu in Israel and Joash in Judah onwards, by further estrangement and reciprocal attacks, which led eventually to the destruction…

The glory of the kingdom of Israel was in its height and perfection in Solomon; it was long in coming to it, but it soon declined, and began to sink and wither in the very next reign, as we find in this chapter, where we have the kingdom divided, and thereby weakened and made little in comparison with what it had been. Here is, I. Rehoboam's accession to the throne and Jeroboam's return out of Egypt (Kg1 12:1, Kg1 12:2). II. The people's petition to Rehoboam for the redress of grievances, and the rough answer he gave, by the advice of his young counsellors, to that petition (Kg1 12:3-15). III. The revolt of the ten tribes thereupon, and their setting up Jeroboam (Kg1 12:16-20). IV. Rehoboam's attempt to reduce them and the prohibition God gave to that attempt (Kg1 12:21-24). V. Jeroboam's establishment of his government upon idolatry (Kg1 12:25-33). Thus did Judah become weak, being deserted by their brethren, and Israel, by deserting the house of the Lord.
