'Taste' in the Bible

All the people came to cause David to eat bread while it was yet day; but David swore, saying, "God do so to me, and more also, if I taste bread, or anything else, until the sun goes down."

I am this day eighty years old. Can I discern between good and bad? Can your servant taste what I eat or what I drink? Can I hear any more the voice of singing men and singing women? Why then should your servant be yet a burden to my lord the king?
