John Gill Commentary 1 Kings 16:3

"behold, I will utterly sweep away Baasha and his house; and I will make thy house like the house of Jeroboam the son of Nebat." — 1 Kings 16:3 (ASV)

Behold, I will take away the posterity of Baasha, and the
posterity of his house
By death, there shall be none of his family remaining in any branch of it:

and I will make thy house like the house of Jeroboam the son of Nebat ;
execute the same judgment on it, and in the same manner, their sins being alike.
