'Taste' in the Bible

And the people came to make David take food, while it was still day, but David with an oath said, May God's punishment be on me if I take a taste of bread or any other thing till the sun has gone down!

I am now eighty years old: good and bad are the same to me; have meat and drink any taste for me now? am I able to take pleasure in the voices of men or women in song? why then am I to be a trouble to my lord the king?
