Leviticus 23:14

You must not eat any bread or roasted or new grain until the very day you have brought this offering to your God. This is to be a permanent statute for the generations to come, wherever you live.

And ye shall eat neither bread, nor parched corn, nor green ears, until the selfsame day that ye have brought an offering unto your God: it shall be a statute for ever throughout your generations in all your dwellings.
