2 Kings 5:16
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. 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.
This is the account of Naaman, commander of the Syrian king's army, a great and honorable man through whom deliverance had been given to Syria, a mighty warrior who was a leper. After he was healed, Elisha swore by the living Lord that he would receive nothing and refused payment even under strong urging, turning down a costly gift. That refusal made clear that the healing was not for sale. It was fitting because the healing was a blessing God had freely given in mercy, not something for which the prophet should accept payment. The declaration of standing before the Lord is a watchword expressing that a servant stands in the Lord's presence, and this consciousness that the message is from God and fills the whole being is the source of power exemplified by Elijah.
