Rabbi Eliezer says: the heifer is no more than one year old and the cow no more than two years old. But the sages ruled: the heifer may be even two years old and the red cow even three or four years old. Rabbi Meir says: even five years old, though she is old. But they did not wait with it so long since it might in the meantime grow some black hairs and [thus] become invalid. Rabbi Joshua said: I only heard of [a cow] that was three years old [shelashit]. They said to him: What does "shelashit" mean? He replied: thus have I heard it without any explanation. Ben Azzai said: I will explain: if you say "shelishit" the meaning is ‘the third’ in number to others, but when you say "shelashit" the meaning is one that is three years old. Similarly they said a vineyard that is "revai." They said to him: what does "revai" mean? He replied: thus have I heard it without any explanation. Ben Azzai said: I will explain: if you say "revii" the meaning is the fourth in number to others, but when you say "revai" the meaning is one that is four years old. Similarly it was ruled: if a man ate in an afflicted house half a loaf, three of which can be made from a kav, he becomes unclean. They said to him: say rather "eighteen of which are made of a se'ah." He replied: thus have I heard it without any explanation. Ben Azzai said: I will explain: when you say, three of which are made of a kav it would not contain hallah, but if you say, eighteen of which are made of a se'ah, it has been reduced by its hallah.

רַבִּי יוֹסֵי הַגְּלִילִי אוֹמֵר, פָּרִים, בְּנֵי שְׁתַּיִם, שֶׁנֶּאֱמַר (במדבר ח), וּפַר שֵׁנִי בֶן בָּקָר תִּקַּח לְחַטָּאת. וַחֲכָמִים אוֹמְרִים, אַף בְּנֵי שָׁלשׁ. רַבִּי מֵאִיר אוֹמֵר, אַף בְּנֵי אַרְבַּע וּבְנֵי חָמֵשׁ כְּשֵׁרִים, אֶלָּא שֶׁאֵין מְבִיאִים זְקֵנִים, מִפְּנֵי הַכָּבוֹד:

Rabbi Yose the Galilean said: bulls must be no more than two years old, for it is said, "And the second bull you shall take for a sin-offering" (Numbers 8:8). But the sages say: they may be even three years old. Rabbi Meir says: even those that are four or five years old are valid, but old animals are not brought out of respect.
