Charles Ellicott Commentary 2 Kings 8:13

"And Hazael said, But what is thy servant, who is but a dog, that he should do this great thing? And Elisha answered, Jehovah hath showed me that thou shalt be king over Syria." — 2 Kings 8:13 (ASV)

But what, is thy servant a dog, that he should do this great thing? —Rather, (You cannot mean it; ) for what is the dog your servant that he should do, etc. Hazael answers in a tone of pretended amazement and self-deprecation. The exaggerated humility of his language betrays the hypocrite.

The Lord hath shewed me. —Compare 1 Kings 19:15, where this same fact was revealed to Elijah. Literally, Jehovah has made me see you king. How Hazael took this announcement we are not told. Bähr says, “Startled by the revelation of his secret plans, Hazael turned away without answering the earnest words of the prophet.”
