John Gill Commentary 2 Kings 9:33

"And he said, Throw her down. So they threw her down; and some of her blood was sprinkled on the wall, and on the horses: and he trod her under foot." — 2 Kings 9:33 (ASV)

And he said, throw her down
Out of the window upon the ground:

so they threw her down ;
took her up, and cast her headlong, as they were bid:

and some of her blood was sprinkled on the wall ;
of the palace where she was:

and on the horses ;
which drew the chariot of Jehu:

and he trod her underfoot ;
with his horses; according to Kimchi, her sentence, and so her death, was stoning, as a retaliation of Naboth; for stoning was done two ways, both by casting down persons on stones, and by casting stones upon them, (See Gill on Acts 7:58).
