2 Kings 10:15-17 English Standard Version (ESV)
15 And 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,[a] “If it is, give me your hand.” So he gave him his hand. And Jehu took him up with him into the chariot. 16 And he said, “Come with me, and see my zeal for the Lord.” So he[b] had him ride in his chariot. 17 And 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.
2 Kings 10:15-17 New International Version (NIV)
15 After he left there, he came upon Jehonadab son of Rekab, who was on his way to meet him. Jehu greeted him and said, “Are you in accord with me, as I am with you?”
“I am,” Jehonadab answered.
“If so,” said Jehu, “give me your hand.” So he did, and Jehu helped him up into the chariot. 16 Jehu said, “Come with me and see my zeal for the Lord.” Then he had him ride along in his chariot.
17 When Jehu came to Samaria, he killed all who were left there of Ahab’s family; he destroyed them, according to the word of the Lord spoken to Elijah.
