Now he's back for the rest of the family.
I think God may have gotten a bit carried away with this one, though. Remember how he told Jeroboam's wife that he was going to kill everyone in the house of Jeroboam "that pisseth against the wall"?
Behold, I will bring evil upon the house of Jeroboam, and will cut off from Jeroboam him that pisseth against the wall. 1 Kings 14:10
Well, usually "wall pissers" are taken to be males, but apparently God killed the entire family, including females.
God didn't do the killing himself, though, this time. He had Baasha do it for him. First Baasha killed Jeroboam's son Nadab, who became king of Israel after Jeroboam died. (Nadab was completely evil, too, just like his dad.)
Nadab the son of Jeroboam began to reign over Israel ... And he did evil in the sight of the LORD, and walked in the way of his father, and in his sin wherewith he made Israel to sin ... and Baasha smote him ... and reigned in his stead. 15:25-28
Then God had Baasha kill Jeroboam's entire family, wall pissers and non wall pissers, alike. "He smote ... any that breathed ... according unto the saying of the Lord."
He smote all the house of Jeroboam; he left not to Jeroboam any that breathed, until he had destroyed him, according unto the saying of the LORD, which he spake by his servant Ahijah the Shilonite: Because of the sins of Jeroboam which he sinned, and which he made Israel sin, by his provocation wherewith he provoked the LORD God of Israel to anger. 15:29-30
The Bible doesn't say whether or not the bodies of the dead family were treated like shit, as God said they would be.
Behold, I ... will take away the remnant of the house of Jeroboam, as a man taketh away dung. 14:10
Or whether God fed their remains to the dogs and the birds, as he said he would.
Him that dieth of Jeroboam in the city shall the dogs eat; and him that dieth in the field shall the fowls of the air eat: for the LORD hath spoken it. 14:11
But I suppose that's what happened.
The text doesn't say how many were killed in this killing, so I'll just say 10.
