2 Kings 10:17 Meaning and Commentary

2 Kings 10:17

And when he came to Samaria, he slew all that remained unto
Ahab in Samaria
All that were in any connection with him, as related to his family, or as ministers of his in civil or religious things:

till he had destroyed him;
his whole house, as he was ordered:

according to the word of the Lord, which he spake to Elijah;
which is observed, to show the exact fulfilment of prophecy, see ( 1 Kings 21:21 ) .

2 Kings 10:17 In-Context

15 Jehu started out again, and on his way he was met by Jonadab son of Rechab. Jehu greeted him and said, "You and I think alike. Will you support me?" "I will," Jonadab answered. "Give me your hand, then," Jehu replied. They clasped hands, and Jehu helped him up into the chariot,
16 saying, "Come with me and see for yourself how devoted I am to the Lord." And they rode on together to Samaria.
17 When they arrived there, Jehu killed all of Ahab's relatives, not sparing even one. This is what the Lord had told Elijah would happen.
18 Jehu called the people of Samaria together and said, "King Ahab served the god Baal a little, but I will serve him much more.
19 Call together all the prophets of Baal, all his worshipers, and all his priests. No one is excused; I am going to offer a great sacrifice to Baal, and whoever is not present will be put to death." (This was a trick on the part of Jehu by which he meant to kill all the worshipers of Baal.)
