Talmud (Rodkinson Edition) — Book 3…
“ While a man must not eat unclean heave-offering he may otherwise make use thereof, as fuel; how canst thou compare this to leaven on Passover, which must not be used in any manner? The only comparison which can be made between the two can be made by comparing grapes or berries which had become unclean heave-offering and cannot even be used as fuel and leaven on Passover. If such grapes or berries had been eaten, I say, no restitution need be made. ”
