1 Kings 15:1 In-Context

1 It was in the eighteenth year of King Yarov'am the son of N'vat that Aviyam began his reign over Y'hudah.

2 He ruled three years in Yerushalayim; his mother's name was Ma'akhah the daughter of Avishalom.

3 He committed all the sins his father had committed before him; he was not wholehearted with ADONAI his God, as David his forefather had been.

4 Nevertheless, for David's sake ADONAI his God gave him a lamp burning in Yerushalayim by establishing his son after him and making Yerushalayim secure.

5 For David had done what was right from ADONAI's perspective; he had not turned away from anything he had ordered him to do, as long as he lived, except in the matter of Uriyah the Hitti.
