John Wesley on 2 Kings 9:13

They hasted - God putting it into their hearts thus readily to own him. Under him - Under Jehu. A ceremony used in the eastern parts towards superiors, in token of reverence to his person, that they would not have his feet to touch the ground, and that they put themselves and their concerns under his feet, and into his disposal. The stairs - In some high and eminent place, whence he might be seen and owned by all the soldiers, who were called together upon this great occasion.
