2 Kings 5:14-16

Young's Literal Translation

¹⁴ And he goeth down and dippeth in Jordan seven times, according to the word of the man of God, and his flesh doth turn back as the flesh of a little youth, and is clean.

¹⁵ And he turneth back unto the man of God, he and all his camp, and cometh in, and standeth before him, and saith, `Lo, I pray thee, I have known that there is not a God in all the earth except in Israel; and now, take, I pray thee, a blessing from thy servant.'

¹⁶ And he saith, `Jehovah liveth, before whom I have stood -- if I take [it];' and he presseth on him to take, and he refuseth.
