2 Samuel 13:2

Y estaba Amnón angustiado hasta enfermar, por Thamar su hermana: porque por ser ella virgen, parecía á Amnón que sería cosa dificultosa hacerle algo.

And Amnon was so vexed, that he fell sick for his sister Tamar; for she was a virgin; and Amnon thought it hard for him to do any thing to her.
