Yoma 56a — the Talmud in English

Here they are

from now

teruma

gedola —

ten

logs, that is: a tenth of the remainder after the teruma, which is close to ten logs [Tosafot] that I will separate later —

They are from now

the first tithe,

and close to

nine

logs [a tenth of what remains after the teruma and the first tithe] will be from now

the second tithe —

And he transfers [

transfers its sanctity ] the second tithe, which he designated by name, onto coins, since this matter can be corrected immediately —

And drinks immediately

and leaves enough for the teruma and the first tithe — which he designated by name — for he does not drink them, and afterward he will separate the teruma and the tithe, and we say: it is clarified retroactively that the teruma and the tithe took effect upon those logs that he separated,

the words of Rabbi Meir.
