Reference for Zevachim 10:14

ניתק אין לא ניתק לא מאי טעמא אמר קרא הוא בהווייתו יהא

Then the remainder of a sin-offering too is indeed offered.<span class="x" onmousemove="('comment',' E.g., if a man sets aside two animals for his sin-offering, in case one is lost the other should be available. When the first is subsequently offered, the second is treated as a guilt-offering whose owner died. Thus a sin-offering too may be brought after death, and yet if it is sacrificed for a different purpose it is invalid; then a guilt-offering too should be invalid, and this justifies Resh Lakish's difficulty.');">⁸</span>
