Rabbi Eliezer says: a [red] cow for the hatat that is pregnant is valid, But the sages say: it is invalid. Rabbi Eliezer says: it may not be bought from non-Jews, But the sages say: it is valid. And not only this, but all sacrifices of the congregation or the individual may be brought from the land of Israel and from outside the land, from new produce and from the old; Except the omer and the two loaves, which may be brought only from new produce and from within the land.

One that is born from the side, the hire of a harlot or the price of a dog is invalid. Rabbi Eliezer says that it is valid, as it says, "You shall not bring the hire of a harlot or the price of a dog into the house of the Lord your God," (Deuteronomy 23:19) and this was not brought into the house. All blemishes that cause consecrated animals to be invalid cause also the [red] cow to be invalid. If one had ridden on it, leaned on it, hung on its tail, crossed a river by its help, doubled up its leading rope, or put one's cloak on it, it is invalid. But if one had only tied it up by its leading rope or made for it a sandal to prevent it from slipping or spread one's cloak on it because of flies, it is valid. This is the general rule: wherever anything is done for its own sake, it remains valid; but if for the sake of another, it becomes invalid.

If a bird rested on it, it remains valid. If a male beast mounted it, it becomes invalid. Rabbi Judah says: if the male was made to mount, it becomes invalid; but if it did so of itself, it remains valid.

If it had two black or white hairs growing within one follicle, it is invalid. Rabbi Judah said: within one kos; if they grew within two kosot that were adjacent to one another, it is invalid. Rabbi Akiva says: even if there were four or five but they were dispersed, they may be plucked out. Rabbi Eliezer says: even as many as fifty. Rabbi Joshua ben Batera says: even if it had but one on its head and one on its tail, it is invalid. If it had two hairs with their roots black and their tips red or with their roots red and their tips black, everything goes according to what is visible, the words of Rabbi Meir. But the sages say: by the root.
