Albert Barnes Commentary 2 Kings 8:9

"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, Thy son Benhadad king of Syria hath sent me to thee, saying, Shall I recover of this sickness?" — 2 Kings 8:9 (ASV)

Every good thing of Damascus - This probably included not only rich robes and precious metals but also the luscious wine of Helbon (which was the drink of the Persian kings), the soft white wool of the Anti-Lebanon mountains (Ezekiel 27:18), damask coverings for couches (Amos 3:12), and numerous luxury goods that the Syrian capital imported from Tyre, Egypt, Nineveh, and Babylon. Forty camels were loaded with these items, and this impressive caravan paraded through the city's streets, delivering the splendid gift intended for the prophet. Eastern ostentation leads donors to make the greatest possible display of their gifts, and each camel would likely have carried only one or two articles to maximize the effect.

Thy son Ben-hadad - This phrase indicates the greatest respect and was undoubtedly used at Ben-hadad's command to incline the prophet favorably toward him. Compare to 2 Kings 6:21.
