Jeroboam's rebellion in the north (see 1 Kings 12:26–33) caused those who truly wanted to worship the Lord to move south. Rehoboam followed the Lord faithfully for three years, but he became unfaithful in the fourth year of his reign (2 Chronicles 12:1). God then quickly punished Rehoboam by sending Shishak to invade from Egypt (2 Chronicles 12:2–5).
