'Intense' in the Bible

Woe to me because of my brokenness—I am severely wounded!I exclaimed, “This is my intense suffering,but I must bear it.”

“Go against [Babylon] the land of Merathaim (Double Rebellion),Go up against it and against the people of Pekod (Punishment).Kill and utterly destroy them,” says the Lord,“And do everything that I have commanded you.”
