I Kings 15:4

The Lord - give him a lamp - That is, a son to succeed him; see Kg1 11:36.

for David's sake did the Lord his God give him a lamp--"A lamp" in one's house is an Oriental phrase for continuance of family name and prosperity. Abijam was not rejected only in consequence of the divine promise to David (see on 1Ki. 11:13-36).

Because David did that which was right in the eyes of the Lord,.... With respect to worship: and turned not aside from anything that he commanded him all the days of his life; especially in matters of religion, nor even in his moral walk and conversation, deliberately, studiously, and with design: save only in the matter of Uriah the Hittite; the killing of him, and other sins which led on to it, and were in connection with it; Abarbinel thinks, because the affair of Bathsheba is not mentioned, that was not reckoned to David as a sin; but no doubt it was, and is included here.

Reign of Abijam (cf., 2 Chron 13). - Abijam reigned three years, and his mother's name was Maacah, daughter (i.e., grand-daughter) of Absalom. We have the same in Ch2 11:20-21; but in Ch2 13:2 she is called Michajahu, daughter of Uriel of Gibeah. If אבישׁלום was without doubt Absalom, the well-known son of David, as we may infer from the fact that this name does not occur again in the Old Testament in connection with any other person, since Absalom had only one daughter, viz., Thamar (Sa2 14:27), who was fifty years old when Solomon died, Maacah must have been a daughter of this Thamar, who had married Uriel of Gibeah, and therefore a grand-daughter of Absalom. This is sustained by Josephus (Ant. viii. 10, 1). The form of the name מיכיהוּ is probably an error in copying for מעכה, as the name is also written in Ch2 11:20, Ch2 11:21, and not a different name, which Maacah assumed as queen, as Caspari supposes (Micha, p. 3, note 4).

In this chapter we have an abstract of the history, I. Of two of the kings of Judah, Abijam, the days of whose reign were few and evil (Kg1 15:1-8), and Asa, who reigned well and long (v. 9-24). II. Of two of the kings of Israel, Nadab the son of Jeroboam, and Baasha the destroyer of Jeroboam's house (Kg1 15:25-34).
