2 Kings 5:15-18

Then Naaman returned to the man of God, he and all the people in his group, and stood before him. He said, “Behold, I know that there is no God in all the earth, except in Israel; so now accept a blessing and gift from your servant.” But Elisha said, “As the LORD lives, before whom I stand, I will accept nothing.” He urged him to take it, but Elisha refused. Naaman said, “If not, then please, let your servant be given a load of earth for a team of mules; for [from this day on] your servant will no longer offer a burnt offering nor a sacrifice to other gods, but only to the LORD, [the God of Israel]. In this matter may the LORD pardon your servant: when my master [the king] goes into the house of [his god] Rimmon to worship there, and he leans on my hand and I bow in the house of Rimmon, when I bow down in the house of Rimmon, may the LORD pardon your servant in this matter [of attending the king when he worships].”
