'Severe' in the Bible

The light of the full moon will be like the sun's glare and the sun's glare will be seven times brighter, like the light of seven days, when the Lord binds up his people's fractured bones and heals their severe wound.

So I will choose severe punishment for them; I will bring on them what they dread, because I called, and no one responded, I spoke and they did not listen. They did evil before me; they chose to do what displeases me."
