2 Kings 10:14

14 And Jehu said, Take ye them quick. And when they had taken them quick, they strangled them in the cistern, beside the chamber, two and forty men; and he left not any of them (alive). (And Jehu said, Take ye them alive. And when they had taken them alive, then they strangled them there at the well, beside the shelter, forty-two men; and he left none of them alive.)

2 Kings 10:14 Meaning and Commentary

2 Kings 10:14

And he said, take them alive
Gave orders to his guards to seize them, and make them captives:

and they took them alive, and slew them at the pit of the
shearing house;
where they washed the sheep when they sheered them;

[even] forty and two men, neither left he any of them;
they being, by their grandmother's side, of the house of Ahab, and so within the commission of Jehu to slay them, at least as he thought; though his chief view might be, lest they should make any pretensions to the crown, being descended from that house, or should hereafter attempt to avenge the death of their relations; but by the judgment of God they were cut off as idolaters.

And Jehu said to him, Whether thine heart is rightful with mine heart, as mine heart is with thine heart? (Is thy heart right with my heart, as my heart is with thy heart?) And Jehonadab said, It is. And Jehu said, If it is, give me thine hand. Which gave his hand to him; and Jehu raised him up to him(self) into his chariot.
