Matthew Poole and continuators on 2 Kings 5:20

20 ¶ But Gehazi the servant of Elisha the man of God, said, Behold, my master hath spared Naaman this Syrian , in not receiving at his hand that which he brought: but as the LORD liveth, I will run after him, and take somewhat of him .

A stranger, and one of that Nation who are the implacable Enemies of Gods people: whom therefore my Master should not have had so much regard to, as to the Lords Prophets, who better deserved and more needed the money which he offered, than Naaman himself did.

He Swears, that he might have some pretence for the action to which he had bound himself by his Oath; not considering, that to Swear to do any wicked action, is so far from excusing it, that it makes it much worse.
