וש"מ דחוי מעיקרא הוי דחוי וש"מ יש דחוי בדמים

[iii] rejection applies to monetary sanctity.<span class="x" onmousemove="('comment',' This animal was sanctified from the very outset only for its value, i.e., that the money which its sale would furnish should be expended for a sacrifice; nevertheless it becomes permanently ineligible for the altar. This excludes the view that might have been held that only an animal that was fit in the first place to be dedicated to the altar can be rendered permanently ineligible.');">³</span> Raba propounded: What [if one declares,] 'Thy half [be betrothed to me] for half a perutah, and thy [other] half for half a perutah'?
