'Lovesick' in the Bible

But Amnon became frustrated because he was so lovesick over his sister Tamar. For she was a virgin, and to Amnon it seemed out of the question to do anything to her.

Sustain me with raisins;refresh me with apricots,for I am lovesick.

Young women of Jerusalem, I charge you:if you find my love,tell him that I am lovesick.
