In this thing the LORD pardon thy servant, that when my master goeth into the house of Rimmon to worship there, and he leaneth on my hand, and I bow myself in the house of Rimmon: when I bow down myself in the house of Rimmon, the LORD pardon thy servant in this thing.

2 Kings 5:18 In this thing the LORD pardon thy servant, that when my master goeth into the house of Rimmon to worship there, and he leaneth on my hand, and I bow myself in the house of Rimmon: when I bow down myself in the house of Rimmon, the LORD pardon thy servant in this thing.

2 Kings 5:20 But Gehazi, the servant of Elisha the man of God, said, Behold, my master hath spared Naaman this Syrian, in not receiving at his hands that which he brought: but, as the LORD liveth, I will run after him, and take somewhat of him.
The verse centers on "lord", "pardon", "servant", "master", "goeth", "house", "rimmon", and "worship". It is saying that the verse draws attention to "lord" and "pardon", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "And Naaman said Shall there not then..." into verse 19's "And he said unto him Go in...", so "lord" and "pardon" belong inside that flow. In 2 Kings context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "lord" and "pardon" with trust shaped by these words, not by a vague optimism outside the passage.
