1 Kings 15:1 In-Context

1 And in the eighteenth year of king Jeroboam the son of Nebat began Abijam to reign over Judah.

2 He reigned three years in Jerusalem; and his mother's name was Maachah, a daughter of Abishalom.

3 And he walked in all the sins of his father, which he had done before him; and his heart was not perfect with Jehovah his God, as the heart of David his father.

4 But for David's sake Jehovah his God gave him a lamp in Jerusalem, setting up his son after him, and establishing Jerusalem;

5 because David did that which was right in the sight of Jehovah, and turned not aside from anything that he commanded him all the days of his life, except in the matter of Urijah the Hittite.
