Verse 5
Rehoboam was between two dangers: on the north he might be attacked by Jeroboam, on the south by Jeroboam‘s ally, Egypt. From this side was the greater peril, and therefore out of the 15 cities fortified, all but three were on the southern or western frontier, where Egypt would be most likely to attack.
Verse 6-7
See Joshua 15:33-36, notes; Joshua 15:48-51, notes; Joshua 15:58-59, notes.
For Adullam see 1 Samuel 22:1 note. It was in the near neighborhood of Socoh Joshua 15:35; but its site cannot be actually fixed. It was a place of great antiquity Genesis 38:1.
Verse 8
For Gath, see Joshua 13:3 note. Its native king, Achish 1 Kings 2:39, is to he regarded, not as an independent monarch, but as one of the many vassal-kings over whom Solomon reigned 2 Chronicles 9:23. For Mareshah, see Joshua 15:44, for Ziph, Joshua 15:55.
Verse 9-10
The site of Adoraim is uncertain. For Lachish, see Joshua 10:3; Azekah, Joshua 10:10; Zorah, Joshua 15:33; Aijalon, Joshua 10:12; Hebron, Joshua 14:15. No one of the cities was really within the limits of the tribe of Benjamin. The writer uses the phrase “Judah and Benjamin” merely as the common designation of the southern kingdom (compare 2 Chronicles 11:12 and 2 Chronicles 11:23).
Verse 14
Jeroboam probably confiscated the Levitical lands for the benefit of this new priesthood. Under these circumstances the priests and Levites emigrated in large numbers to the southern kingdom; an act which was followed by a general emigration of the more pious Israelites 2 Chronicles 11:16.
Verse 15
The high places - i. e., the two sanctuaries at Dan and Bethel.
For the devils - literally, “for the goats:” probably the word is used (as in Leviticus 17:7) for objects of idolatrous worship generally.
Verse 17
Three years - i. e., during the first three years of Rehoboam‘s reign. In the fourth year an apostasy took place, which neutralized all the advantages of the immigration (marginal reference). In the fifth the apostasy was punished by the invasion and success of Shishak 2 Chronicles 12:2.
Verse 18
This is probably an extract from the “genealogies” of Iddo 2 Chronicles 12:15.
As Jerimoth is not mentioned among the legitimate sons of David 1 Chronicles 3:1-8; 1 Chronicles 14:4-7, he must have been the child of a concubine.
Abihail was probably the “grand-daughter,” not “daughter,” of Eliab 1 Samuel 16:6; 1 Samuel 17:13; 1 Chronicles 2:13.
Verse 20
Maachah the daughter of Absalom - Rather, “grand-daughter” (see the 1 Kings 15:2 note).
Verse 22
Jeush was probably the oldest of Rehoboam‘s sons, and should naturally and according to the provisions of the Law Deuteronomy 21:15-17 have been his heir. But Rehoboam‘s affection for Maachah led him to transgress the Law.
Verse 23
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 which might well content them and prevent them from being jealous of Abijah.
He desired many wives - (Compare 2 Chronicles 11:21). Some prefer to connect the words with the preceding words. If so, they denote another point in which Rehoboam was careful to please his sons.
