John Gill Commentary 1 Kings 16:13

"for all the sins of Baasha, and the sins of Elah his son, which they sinned, and wherewith they made Israel to sin, to provoke Jehovah, the God of Israel, to anger with their vanities." — 1 Kings 16:13 (ASV)

For all the sins of Baasha, and the sins of Elah his son
By which it appears that the son trod in the steps of his father, and was therefore cut off:

by which they sinned, and by which they made Israel to sin, in
provoking the Lord God of Israel to anger with their vanities
their idols, which had nothing in them, and cannot be of any service to their worshippers; and to serve such, and neglect the worship of the true God, and draw others into the same iniquity, must be very provoking to the most High.
