'Taste' in the Bible

And all the people come to cause David to eat bread while yet day, and David sweareth, saying, 'Thus doth God to me, and thus He doth add, for -- before the going in of the sun, I taste no bread or any other thing.'

A son of eighty years I am to-day; do I know between good and evil? doth thy servant taste that which I am eating, and that which I drink? do I hearken any more to the voice of singers and songstresses? and why is thy servant any more for a burden unto my lord the king?
