This is the common refrain in these chapters: doing what is evil in the sight of the Lord, following the example of Jeroboam, who led the people of Israel to sin. This always concerns the worshipping of images with bull calves in Bethel—that contagious sin. It is striking that, although Baasha executed the punishment of God on the family of Jeroboam, he was, nevertheless, guilty of the same sin. Thus, you already anticipate what will be told next.
34 He did what was evil in the sight of the LORD and walked in the way of Jeroboam and in his sin which he made Israel to sin.
