2 Kings 10:15-20
English Standard Version
Chapter 10
15And when he departed from there, he met Jehonadab the son of Rechab coming to meet him. And he greeted him and said to him, "Is your heart true to my heart as mine is to yours?" And Jehonadab answered, "It is." Jehu said, "If it is, give me your hand." So he gave him his hand. And Jehu took him up with him into the chariot. 16And he said, "Come with me, and see my zeal for the Lord." So he had him ride in his chariot. 17And when he came to Samaria, he struck down all who remained to Ahab in Samaria, till he had wiped them out, according to the word of the Lord that he spoke to Elijah.
18Then Jehu assembled all the people and said to them, "Ahab served Baal a little, but Jehu will serve him much.
19Now therefore call to me all the prophets of Baal, all his worshipers and all his priests. Let none be missing, for I have a great sacrifice to offer to Baal. Whoever is missing shall not live." But Jehu did it with cunning in order to destroy the worshipers of Baal.
20And Jehu ordered, "Sanctify a solemn assembly for Baal." So they proclaimed it.
