KJV:
Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the LORD bindeth up the breach of his people, and healeth the stroke of their wound.
NASB:
The light of the moon will be as the light of the sun, and the light of the sun will be seven times brighter, like the light of seven days, on the day the LORD binds up the fracture of His people and heals the bruise He has inflicted.
