'Sing' in the Bible

They'll sing this mourning song for you: "How lost you are, you inhabited city, that was built in the middle of the sea! How famous you were! How strong on the sea! She and her inhabitants inflicted terror to everyone who lived within her."

As far as they are concerned, you sing romantic songs with a beautiful voice and play a musical instrument well. They'll listen to what you have to say, but they won't put it into practice!
