And Elisha said unto him, Go, say unto him, Thou mayest certainly {f} recover: howbeit the LORD hath shewed me that he shall surely die.

(f) Meaning that he would recover of this disease: but he knew that this messenger Hazael would slay him to obtain the kingdom.

Wesley's Notes

8:10 Howbeit - Here is no contradiction: for the first words contain an answer to Benhadad's question, shall I recover? To which the answer is, thou mayest, notwithstanding thy disease, which is not mortal. The latter words contain the prophet's addition to that answer, which is, that he should die, not by the power of his disease, but by some other cause.

Jamieson-Fausset-Brown Bible Commentary

10. Go, say . Thou mayest certainly recover-There was no contradiction in this message. This part was properly the answer to Ben-hadad's inquiry [2Ki 8:9]. The second part was intended for Hazael, who, like an artful and ambitious courtier, reported only as much of the prophet's statement as suited his own views (compare 2Ki 8:14).

Matthew Henry's Concise Commentary

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.
