But what, is thy servant a dog? - This is a mistranslation, and conveys to the English reader a sense quite different from that of the original. Hazael's speech runs thus - "But what is thy servant, this dog, that he should do this great thing?" He does not shrink from Elisha's words, or mean to say that he would be a dog, could he act so cruelly as Elisha predicts he will. On the contrary, Elisha's prediction has raised his hopes, and his only doubt is whether so much good fortune ("this great thing") can be in store for one so mean. "Dog" here, as generally (though not always) in Scripture, has the sense of "mean," "low," "contemptible."

But what, is thy servant a dog, that he should do this great things - I believe this verse to be wrongly interpreted by the general run of commentators. It is generally understood that Hazael was struck with horror at the prediction; that these cruelties were most alien from his mind; that he then felt distressed and offended at the imputation of such evils to him; and yet, so little did he know his own heart, that when he got power, and had opportunity, he did the whole with a willing heart and a ready hand. On the contrary, I think he was delighted at the prospect; and his question rather implies a doubt whether a person so inconsiderable as he is shall ever have it in his power to do such great, not such evil things; for, in his sight, they had no turpitude. The Hebrew text stands thus: כי מה עבדך הכלב כי יעשה הדבר הגדול הזה ki mah abdecha hakkeleb, ki yaaseh haddabar haggadol hazzeh? "But, what! thy servant, this dog! that he should do this great work!" Or, "Can such a poor, worthless fellow, such a dead dog, [ὁ κυων ὁ τεθνηκως, Sept.], perform such mighty actions? thou fillest me with surprise." And that this is the true sense, his immediate murder of his master on his return fully proves. "Our common version of these words of Hazael," as Mr. Patten observes, "has stood in the front of many a fine declamation utterly wide of his real sentiment. His exclamation was not the result of horror; his expression has no tincture of it; but of the unexpected glimpse of a crown! The prophet's answer is plainly calculated to satisfy the astonishment he had excited. A dog bears not, in Scripture, the character of a cruel, but of a despicable animal; nor does he who is shocked with its barbarity call it a Great deed." - David Vindicated.

And Hazael said, but what, is thy servant a dog, that he should do this great thing?.... What dost thou take me to be, a vile, impudent, fierce, and cruel creature, as a dog, to be guilty of so great inhumanity and barbarity as this? or what is thy servant? a dog, a mean abject creature, of no power and authority, incapable of doing such great things spoken of? to which sense not only what is predicted of him, said to be great, inclines, but what follows:

and Elisha answered, the Lord hath showed me that thou shall be king over Syria; and that thou shalt have power enough to do this; this declaration, according to Ben Gersom, was the anointing of him, predicted 1 Kings 19:15.

But when Hazael replied in feigned humility, What is thy servant, the dog (i.e., so base a fellow: for כּלב see at 1 Samuel 24:15), that he should do such great things? Elisha said to him, "Jehovah has shown thee to me as king over Aram;" whereupon Hazael returned to his lord, brought him the pretended answer of Elisha that he would live (recover), and the next day suffocated him with a cloth dipped in water. מכבּר, from כּבר, to plait or twist, literally, anything twisted; not, however, a net for gnats or flies (Joseph., J. D. Mich., etc.), but a twisted thick cloth, which when dipped in water became so thick, that when it was spread over the face of the sick man it was sufficient to suffocate him.

And Hazael said, But what, is thy servant {g} a dog, that he should do this great thing? And Elisha answered, The LORD hath shewed me that thou shalt be king over Syria.

(g) That I should be without all humanity and pity.

8:13 A dog - So fierce, barbarous, and inhuman. King - And when thou shalt have power in thy hand, thou wilt discover that bloody disposition, and that hatred against God's people, which now lies hid from others, and possibly from thyself.

8:7-15 Among other changes of men's minds by affliction, it often gives other thoughts of God's ministers, and teaches to value the counsels and prayers of those whom they have hated and despised. It was not in Hazael's countenance that Elisha read what he would do, but God revealed it to him, and it fetched tears from his eyes: the more foresight men have, the more grief they are liable to. It is possible for a man, under the convictions and restraints of natural conscience, to express great abhorrence of a sin, yet afterwards to be reconciled to it. Those that are little and low in the world, cannot imagine how strong the temptations of power and prosperity are, which, if ever they arrive at, they will find how deceitful their hearts are, how much worse than they suspected. The devil ruins men, by saying they shall certainly recover and do well, so rocking them asleep in security. Hazael's false account was an injury to the king, who lost the benefit of the prophet's warning to prepare for death, and an injury to Elisha, who would be counted a false prophet. It is not certain that Hazael murdered his master, or if he caused his death it may have been without any design. But he was a dissembler, and afterwards proved a persecutor to Israel.
