Albert Barnes Commentary 2 Chronicles 11:23

"And he dealt wisely, and dispersed of all his sons throughout all the lands of Judah and Benjamin, unto every fortified city: and he gave them victuals in abundance. And he sought [for them] many wives." — 2 Chronicles 11:23 (ASV)

Rehoboam’s wisdom was shown:

1. In dispersing his other sons instead of allowing them to remain together in Jerusalem, where they might have joined in a plot against Abijah, as Adonijah and his brothers had done against Solomon (1 Kings 1:5–10).
2. In giving his sons positions that would content them and prevent them from being jealous of Abijah.

He desired many wives — (Compare 2 Chronicles 11:21). Some prefer to connect this phrase with the preceding words. If so, it denotes another point in which Rehoboam was careful to please his sons.
