'Acute' in the Bible

Now when He rose and left the synagogue He went to Simon's house. Simon's mother-in-law was suffering from an acute attack of fever; and they consulted Him about her.

For the love of money [that is, the greedy desire for it and the willingness to gain it unethically] is a root of all sorts of evil, and some by longing for it have wandered away from the faith and pierced themselves [through and through] with many sorrows.
