II Chronicles 12:8

But (כּי after a negative clause) they shall be his servants, sc. for a short time (see Ch2 12:7), "that they may know my service, and the service of the kingdoms of the countries" (cf. Ch1 29:30); i.e., that they may learn to know by experience the difference between the rule of God and that of the heathen kings, and that God's rule was not so oppressive as that of the rulers of the world.

This chapter gives us a more full account of the reign of Rehoboam than we had before in Kings and it is a very melancholy account. Methinks we are in the book of Judges again; for, I. Rehoboam and his people did evil in the sight of the Lord (Ch2 12:1). II. God thereupon sold them into the hands of Shishak, king of Egypt, who greatly oppressed them (Ch2 12:2-4) III. God sent a prophet to them, to expound to them the judgment and to call them to repentance (Ch2 12:5). IV. They thereupon humbled themselves (Ch2 12:6). V. God, upon their repentance, turned from his anger (Ch2 12:7, Ch2 12:12) and yet left them under the marks of his displeasure (Ch2 12:8-11). Lastly, Here is a general character of Rehoboam and his reign, with the conclusion of it (Ch2 12:13-16).
