After meeting with Ahaziah's family (and killing them all), Jehu got into his chariot and drove away furiously toward Samaria. On his way he ran across an old friend, Jehonadab.
Jehu asked Jehonadab, "Is your heart as true to mine as mine is to yours?" And Jehonadb said, "It is." (I guess they were really good friends.)
When he was departed thence, he lighted on Jehonadab the son of Rechab coming to meet him: and he saluted him, and said to him, Is thine heart right, as my heart is with thy heart? And Jehonadab answered, It is. 2 Kings 10:15aThen Jehu said, "If it is, give me your hand." (This is getting so romantic!)
If it be, give me thine hand. 2 Kings 10:15bSo Jehu reached out his hand and took Jehonadab into the chariot.
And he gave him his hand; and he took him up to him into the chariot. 2 Kings 10:15cWhen Jehonadab and Jehu were finally together, Jehu said, "Come with me, and see my zeal for the Lord."
And he said, Come with me, and see my zeal for the LORD. 2 Kings 10:16Then the two men, whose hearts were true to each other, rode off into the sunset toward Samaria.
When they arrived in Samaria, they slaughtered the rest of Ahab's family, "according to the saying of the LORD, which he spake to Elijah."
And when he came to Samaria, he slew all that remained unto Ahab in Samaria, till he had destroyed him, according to the saying of the LORD, which he spake to Elijah. 2 Kings 10:17And by so doing, the true-hearted partners expressed their zeal for the Lord.
The Bible doesn't say how many were killed, so I just guessed 100.
There really should be a Brick Testament story for this one!
God's next killing: Jehu assembles the followers of Baal and then slaughters them all
