 However, the mundane use of "maaser sheni" was not considered "me'ilah" (unauthorized or inappropriate use of Temple property/"hekdesh").Every three years, on the "mincha" (afternoon service) of the last day of Pesach (Passover), they would say the "Vidui Maaser" (a confession of tithing prescribed specifically in the Torah).The reason this is done at the end of the festival, at the last prayer is because until that time (during the Temple era), people were still eating their "Maaser Sheni".
