'Extreme' in the Bible

This brought extreme grief to Isaac and Rebekah.

Extreme hunger came to all the land of Egypt, and the people cried out to Pharaoh for food. Pharaoh told all Egypt, “Go to Joseph and do whatever he tells you.”

When they came to the threshing floor of Atad, which is beyond the Jordan, they mourned there with a great lamentation (expressions of mourning for the deceased) and [extreme demonstrations of] sorrow [according to Egyptian custom]; and Joseph observed a seven-day mourning for his father.
