Mizmor Lesoda on Erev Pesach

Pesach

Sources address why the psalm of thanksgiving (Mizmor Lesoda) is not recited on the eve of Passover. The halakhic reasoning centers on the thanksgiving offering whose bread is chametz, creating a prohibition against bringing such an offering even on Erev Pesach to avoid issues with leftover chametz.

שלחמי תודה היו חמץ ואפילו בער״פ אסור להקריבה
