'Special' in the Bible

A potter has the right to do what he wants to with his clay, doesn't he? He can make something for a special occasion or something for ordinary use from the same lump of clay.

The one who observes a special day, observes it to honor the Lord. The one who eats, eats to honor the Lord, since he gives thanks to God. And the one who does not eat, refrains from eating to honor the Lord; yet he, too, gives thanks to God.
