Reference for Terumot 1:3

קָטָן שֶׁלֹּא הֵבִיא שְׁתֵּי שְׂעָרוֹת, רַבִּי יְהוּדָה אוֹמֵר, תְּרוּמָתוֹ תְרוּמָה. רַבִּי יוֹסֵי אוֹמֵר, אִם עַד שֶׁלֹּא בָא לְעוֹנַת נְדָרִים, אֵין תְּרוּמָתוֹ תְרוּמָה. וּמִשֶׁבָּא לְעוֹנַת נְדָרִים, תְּרוּמָתוֹ תְרוּמָה:

Regarding a minor who has not brought forth two [pubic] hairs, Rabbi Yehudah says that his <i>Terumah</i> is [valid] <i>Terumah</i>. Rabbi Yosi says, if he has not reached an age of [responsibility for his] vows, his <i>Terumah</i> is not [valid] <i>Terumah</i>. When he reaches an age [of responsibility for his] vows, his <i>Terumah</i> is [valid] <i>Terumah</i>.
