John Gill Commentary 2 Kings 9:36

"Wherefore they came back, and told him. And he said, This is the word of Jehovah, which he spake by his servant Elijah the Tishbite, saying, In the portion of Jezreel shall the dogs eat the flesh of Jezebel;" — 2 Kings 9:36 (ASV)

Wherefore they came again, and told him
How things were, and what only could be found of Jezebel:

and he said, this is the word of the Lord ;
or the fulfilment of it:

which he spoke by his servant Elijah the Tishbite, saying ;
as in (1 Kings 21:23) .
