Matthew Poole and continuators on 2 Kings 5:16

16 But he said, As the LORD liveth before whom I stand, I will receive none: and he urged him to take it, but he refused .

Not that he thought it simply unlawful to receive Gifts or Presents, which he did receive from others, chap. 4. 42. but because of the special circumstances of the present case; this being much for the Honour of the True God and Religion, that the Syrians should see the generons Piety, and Charity, and Kindness of his Ministers and Servants, and how much they despised all that Worldly wealth and glory, which the Priests or Prophets of the Gentiles so greedily sought after; and that hereby Naaman might be much confirmed in that Good Religion which he had embraced, and others might be brought to a love and liking of it.
