1 Kings 15:3

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.

1 Kings 15:3 In-Context

1 Now in the eighteenth year of king Jeroboam the son of Nebat began Abijam to reign over Judah.
2 Three years reigned he in Jerusalem: and his mother's name was Maacah the 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 Nevertheless for David's sake did Jehovah his God give him a lamp in Jerusalem, to set up his son after him, and to establish Jerusalem;
5 because David did that which was right in the eyes of Jehovah, and turned not aside from anything that he commanded him all the days of his life, save only in the matter of Uriah the Hittite.
