'Taste' in the Bible

And all the people came to cause David to eat bread while it was yet day; but David sware, saying, God do so to me, and more also, if I taste bread, or aught else, till the sun be down.

I am this day fourscore years old: can I discern between good and bad? can thy servant taste what I eat or what I drink? can I hear any more the voice of singing men and singing women? wherefore then should thy servant be yet a burden unto my lord the king?
