אמר רבא קסבר רבי יהודה כל שהוא מין במינו ודבר אחר סלק את מינו כמי שאינו ושאינו מינו רבה עליו ומבטלו:
Raba answered, R'Judah is of the opinion that where an element is mixed with like kind and also with another kind, you must disregard the like kind as if it were not there, and the other kind, if more in quantity, will neutralize [the element].<span class="x" onmousemove="('comment',' The case dealt with by R. Judah in our Mishnah is where the handful, which is made up of oil and flour, was mixed with one of the meal-offerings mentioned, which also contains oil. Now the oil in the handful is disregarded, so that the flour of the handful will neutralize the oil of the other meal-offering which it has absorbed, with the result that the handful has had too much oil and is therefore invalid.');"><sup>1</sup></span> It was reported: If [the priest] poured oil on the handful taken from the sinner's meal-offering, R'Johanan maintains it is invalid; but Resh Lakish says, He should in the first instance wipe up with it the remains of the log of oil and then offer it.<span class="x" onmousemove="('comment',' It is the proper thing, maintains Resh Lakish, to scrape up with the handful of the sinner's meal-offering any oil that may be found remaining in the log measure which had been used for some other meal-offering. Accordingly if he actually poured some oil on the handful it is certainly valid.');"><sup>2</sup></span>
