Kings III 16:12 In-Context

10 And Zambri went in and smote him and slew him, and reigned in his stead.
11 And it came to pass when he reigned, when he sat upon his throne,
12 that he smote all the house of Baasa, according to the word which the Lord spoke against the house of Baasa, and to Ju the prophet,
13 for all the sins of Baasa and Ela his son, as he led Israel astray to sin, to provoke the Lord God of Israel with their vanities.
14 And the rest of the deeds of Ela which he did, behold, are not these written in the book of the chronicles of the kings of Israel?
