Reference for Temurah 42:5

מעשר חולין הוא

Throughout the Torah we can derive by inference one rule from another which has itself been derived by inference, save only in the field of dedications where we do not derive a rule from one which is itself derived? - Tithe [of grain] is [considered] hullin.<span class="x" onmousemove="('comment',' Because it can he redeemed to become hullin i.e., unconsecrated grain, and eaten in all places (R. Gershom) . Therefore when we compare second tithe with firstling, we are not really making analogy between dedications, as is the case when we inferred 'flesh' from 'blood'.');">⁵</span>
