What does 2 Kings 8:11 mean?

The king said to Hazael, “Take a present in your hand, and go, meet the man of God, and inquire of Yahweh by him, saying, ‘Will I recover from this sickness?’”

So Hazael went to meet him, and took a present with him, even of every good thing of Damascus, forty camels’ burden, and came and stood before him, and said, “Your son Benhadad king of Syria has sent me to you, saying, ‘Will I recover from this sickness?’”

Elisha said to him, “Go, tell him, ‘You will surely recover;’ however Yahweh has shown me that he will surely die.”

Hazael said, “Why do you weep, my lord?” He answered, “Because I know the evil that you will do to the children of Israel. You will set their strongholds on fire, and you will kill their young men with the sword, and will dash their little ones in pieces, and rip up their pregnant women.”

Hazael said, “But what is your servant, who is but a dog, that he could do this great thing?” Elisha answered, “Yahweh has shown me that you will be king over Syria.”

Then he departed from Elisha, and came to his master, who said to him, “What did Elisha say to you?” He answered, “He told me that you would surely recover.”
