'Love' in the Bible

I am full of grief for you, my brother Jonathan: very dear have you been to me: your love for me was a wonder, greater than the love of women.

Now after this, it came about that Absalom, David's son, had a beautiful sister, whose name was Tamar; and David's son Amnon was in love with her.

And he was so deeply in love that he became ill because of his sister Tamar; for she was a virgin, and so it seemed hard to Amnon to do anything to her.

And he said to him, O son of the king, why are you getting thinner day by day? will you not say what your trouble is? And Amnon said to him, I am in love with Tamar, my brother Absalom's sister.

Then Amnon was full of hate for her, hating her with a hate greater than his earlier love for her. And he said to her, Get up and be gone.

And Absalom said, Is this your love for your friend? why did you not go with your friend?
