Answer: Salve for their eyes

He counsels them to buy refined gold, white garments to cover their nakedness, and salve to anoint their eyes so they may see.

“I counsel you to buy from Me gold refined by fire so that you may become rich, white garments so that you may be clothed and your shameful nakedness not exposed, and salve to anoint your eyes so that you may see.”— Revelation 3:18 (BSB)
