Musar על יומא 141:7

The elevation was to such an extent that its kind, all over the world, was blessed, as our sages stated in a Midrash. So too, the food and drink which the holy man eats elevates that food or drink as if it had actually been offered on the altar. This is similar to what our sages, of blessed memory, said: "one who brings a gift to a Torah scholar is as if he had offered first-fruits (Bikurim)" (Ketuvot 105b), and "[if a man wishes to offer a wine libation upon the altar], let him fill the throat of the Torah scholars with wine" (Yomah 71a).
