He walked in the way of the house of Ahab and did evil in the eyes of Yahweh, as the house of Ahab; for he [was] the son-in-law of the house of Ahab.

But he did not execute the sons of the assassins. He obeyed the Lord's commandment as recorded in the law scroll of Moses, "Fathers must not be put to death for what their sons do, and sons must not be put to death for what their fathers do. A man must be put to death only for his own sin."

To this day they do after their former customs: they fear not Jehovah, neither do they after their statutes or after their ordinances, nor after the law and commandment that Jehovah commanded the sons of Jacob, whom he named Israel.

And it happened, these nations feared Jehovah, and they served their graven images, both their sons and their sons' sons, as their fathers did, they do until this day.

When Elisha returned to Gilgal, there was a famine in the land. The sons of the prophets were sitting at his feet. He said to his attendant, “Put on the large pot and make stew for the sons of the prophets.”

Since Ahab had 70 sons in Samaria, Jehu wrote letters and sent them to Samaria to the rulers of Jezreel, to the elders, and to the guardians of Ahab’s sons, saying:

Then Jehu wrote them a second letter, saying:

If you are on my side, and if you will obey me, bring me the heads of your master’s sons at this time tomorrow at Jezreel.

All 70 of the king’s sons were being cared for by the city’s prominent men.

Jehu met the relatives of Ahaziah king of Judah and asked, “Who are you?”

They answered, “We’re Ahaziah’s relatives. We’ve come down to greet the king’s sons and the queen mother’s sons.”

Now there cried a certain woman of the wives of the sons of the prophets unto Elisha, saying, Your servant my husband is dead; and you know that your servant did fear the LORD: and the creditor has come to take unto him my two sons to be slaves.

Now the king's sons, totaling 70 men, were living with the leading men of the city, who were their guardians. When the letter from Jehu arrived, the city leaders arrested the king's sons, slaughtered all 70 of them, put their heads in baskets, and sent them to Jehu at Jezreel.
