John Gill Commentary 2 Kings 10:5

"And he that was over the household, and he that was over the city, the elders also, and they that brought up [the children], sent to Jehu, saying, We are thy servants, and will do all that thou shalt bid us; we will not make any man king: do thou that which is good in thine eyes." — 2 Kings 10:5 (ASV)

And he that was over the house
The king's palace in Samaria, who had the custody, care, and government of it:

and he that was over the city ;
the commander and governor of it, that had the highest post in it under the king;

the elders also
all other subordinate officers and magistrates:

and the bringers up of the children ;
who had the education of the king's sons committed to them:

sent to Jehu, saying, we are your servants, and will do all that you
shall bid us .
They were ready to do homage, and swear allegiance to him as their king, and obey all his commands as
faithful subjects:

we will not make any king ;
or set up any on the throne, no, not any of the sons or grandsons of Ahab:

do you that which is good in your eyes ,
we will never oppose you.
