ספורנו — אם על תודה יקריבנו / חלות מצות / לחם חמץ

Q — Why does korban Todah require FOUR varieties of bread, ten loaves of each — forty loaves total — when other shelamim require no bread at all? And why is its eating time shortened to day-and-night (like kodshei kodashim), not the usual two-day window for shelamim?

A — For Sforno, the entire architecture of the korban serves one goal: *publicizing the nes*. "ברבות הלחם יתפרסם הנס לאוכלים רבים" — abundance of bread guarantees many eaters, which guarantees many witnesses to the story of the נס recounted at the meal. The short eating window reinforces this: a lot of food + a small time window = enforced sharing, enforced gathering. Korban Todah is structurally a publicity event, not just a private thanks. A nes lived through privately is not yet the full avodah of toda; the toda is completed only when others come to hear it. The halachic shape of the korban encodes its social purpose.
