Bava Batra 103A

אין נמדדין עמה. פחות מכאן ⁠– נמדדין עמה.

they are not measured together with the rest of the field. If the crevices or rocks were less than 10 handbreadths, they are measured together with the rest of the field.

ואמאי? ליקדשו באנפי נפשייהו! וכי תימא: כיון דלא הוי בית כור, לא קדשי;

The Talmud asks: But why are the crevices that are deeper and the rocks that are higher than 10 handbreadths not measured with the rest of the field? Let them at least be consecrated separately and require their own redemption. And if you would say that since they are not the size of a beit kor, they cannot be consecrated, there is a difficulty.

והא תניא: ״שדה״⁠ – מה תלמוד לומר? לפי שנאמר: ״זרע חמר שערים בחמשים שקל כסף״; אין לי אלא שהקדיש בענין הזה,

But isn’t it taught in a baraita concerning the verse: “And if he that sanctified the field will redeem it” (Leviticus 27:19): Why must the verse state the word “field”? Since the previous verses are all discussing a field, it would have sufficed for this verse to refer to the field with the pronoun: It. Rather, as it is stated in an earlier verse: “Then your valuation should be according to the seed required for it; a ḥomer of barley seed should be valued at 50 shekels of silver” (Leviticus 27:16), I have derived only the halakha in the case of one who consecrated in this manner, i.e., an area fit to sow a ḥomer of barley seed.

מנין לרבות לתך וחצי לתך, סאה, תרקב וחצי תרקב? תלמוד לומר: ״שדה״, מכל מקום!

The baraita continues: From where do I learn that this halakha is also meant to include the case of one who consecrated a smaller area, e.g., an area fit to sow a letekh, i.e., a half-kor, a half-letekh, a se’a, a tarkav, and a half-tarkav? From where is it derived that these smaller plots of land can also be consecrated and redeemed in accordance with the fixed values stated in the Torah? The verse states: “A field,” teaching that this halakha applies in any case of a field, even to smaller plots.
