A minor girl from one day old until she brings forth two [pubic] hairs—she has [right of] sale [i.e. that her father can sell her into slavery] and has no fine [if she is raped etc.]—words of Rabbi Meir. For Rabbi Meir used to say: Anytime there is [the right of] sale, there is no fine; and any time there is a fine, there is no [right of] sale. But the Sages say: A minor girl from three years old and one day until she becomes an adult has a fine.
