2 Kings 5:15-16

15And he returned to the man of God, he and all his aides, and came and stood before him; and he said, “Indeed, now I know that there is no God in all the earth, except in Israel; now therefore, please take a gift from your servant.”

16But he said, “As the Lord lives, before whom I stand, I will receive nothing.” And he urged him to take it, but he refused.
