Eating the Second Tithe while Ritually Impure
"Neither have I consumed of it while impure"—Deuteronomy 26:14.
It is forbidden to consume of the Second Tithe while ritually impure – even in Jerusalem – until the produce is "redeemed" [i.e., it is exchanged for money or other, pure, produce].
This prohibition applies whether the individual eating is impure or if the produce itself is impure.
An "Onen" Eating from the Second Tithe
"I have not eaten of it while an onen"—Deuteronomy 26:14.
An onen [the next of kin of a deceased, in the period before the deceased's burial] may not eat from the Second Tithe—or from any sacrificial offerings.
