Talmud for Pesachim 57:7

The colleagues said, in the fifth [hour] following Rebbi Jehudah if he dedicated it it is dedicated¹³⁸In order to avoid having to burn the leavened matter, he dedicates it to the Temple to be sold and the proceeds used for the Temple’s needs. Temple property is not subject to the prohibition of leavened matter since it is not yours as mentioned in Ex.13:7.; if he designated it as heave it is no heave. If he dedicated it it is dedicated, dedication of money’s worth¹³⁹Even for R. Jehudah the biblical prohibition of usufruct only starts on midday of the 14^th; during the fifth hour the matter is worth money even for Jews, since it may be used as cattle feed.. If he designated it as heave it is no heave, since heave was given only to be consumed¹⁴⁰Heave is a sanctum to be given to the Cohen to be consumed in purity; nothing pure that cannot be consumed may become heave.. Rebbi Yose told them, the opposite is reasonable. If he dedicated it it is not dedicated; if he designated it as heave it is heave. If he dedicated it it is not dedicated, since one does not redeem sancta to feed to the dogs¹⁴¹Babli 29a, Ševuot 11b, Bekhorot 15a, Temurah 17a,30b,31a; Yerushalmi Maˋaser Šeni 2:5 Note 82.. If he designated it as heave it is heave, since it is pure by the words of the Torah¹⁴²Since by biblical standards it is food until 12 am, a rabbinic prohibition cannot invalidate a biblically valid dedication. This cannot be compared with the case of preliminary marriage since there money’s worth is required, which was eliminated by rabbinic usage.. You are the one who decided that it has to be burned.
