'Crumbs' in the Bible

and sandals, old and patched, on their feet, and old garments upon them, and all the bread of their provision is dry -- it was crumbs.

this our bread -- hot we provided ourselves with it out of our houses, on the day of our coming out to go unto you, and now, lo, it is dry, and hath been crumbs;

and thou hast taken in thy hand ten loaves, and crumbs, and a bottle of honey, and hast gone in unto him; he doth declare to thee what becometh of the youth.'
