"The proud spirit of Naaman rebelled against following the course outlined by Elisha. The rivers mentioned by the Syrian captain were beautified by surrounding groves, and many flocked to the banks of these pleasant streams to worship their idol gods. It would have cost Naaman no great humiliation of soul to descend into one of those streams. But it was only through following the specific directions of the prophet that he could find healing. Willing obedience alone would bring the desired result. PK 249.1"
"And Elisha sent a messenger unto him, saying, Go and wash in Jordan seven times, and thy flesh shall come again to thee, and thou shalt be clean."
EGW directly references the story of Naaman and Elisha, elaborating on Naaman's pride and the importance of following specific instructions for healing, which is directly based on 2 Kings 5:10.
"clean?” The faith of Naaman was being tested, while pride struggled for the mastery. But faith conquered, and the haughty Syrian yielded his pride of heart and bowed in submission to the revealed will of Jehovah. Seven times he dipped himself in Jordan, “according to the saying of the man of God.” And his faith was honored; “his flesh came again like unto the flesh of a little child, and he was clean.” PK 249.2"
"Then went he down, and dipped himself seven times in Jordan, according to the saying of the man of God: and his flesh came again like unto the flesh of a little child, and he was clean."
EGW directly quotes 2 Kings 5:14.
"Gratefully “he returned to the man of God, he and all his company,” with the acknowledgment, “Behold, now I know that there is no God in all the earth, but in Israel.” PK 249.3"
"And he returned to the man of God, he and all his company, and came, and stood before him: and he said, Behold, now I know that there is no God in all the earth, but in Israel: now therefore, I pray thee, take a blessing of thy servant."
This passage directly alludes to Naaman's declaration in 2 Kings 5:15 after being healed.
