Jehoram was in firm control of the kingdom. He had all his brothers killed, and also some Israelite officials.

He went to his father's house at Ophrah. There on top of a single stone he killed his seventy brothers, Gideon's sons. Gideon's youngest son Jotham hid and therefore was not killed.

While they were in the field, Cain attacked his brother Abel and killed him.

They invaded Judah and stole the royal property from the palace. They led Jehoram's wives and sons away as prisoners. The only one left behind was Ahaziah, his youngest son.

When King Ahaziah's mother Athaliah learned of her son's murder, she gave orders for all the members of the royal family of Judah to be killed.

Thus God paid Abimelech back for the crime that he committed against his father in killing his seventy brothers.

Jehu carried out God's sentence on the dynasty. He came across a group made up of Judean leaders and of Ahaziah's nephews that had accompanied Ahaziah on his visit. Jehu killed them all.

We should not be like Cain who was of the evil one, and killed his brother. Why did he murder him? It was because his works were evil, and his brother's were righteous.
