וְאִם־לֹא֩ תַשִּׂ֨יג יָד֜וֹ לִשְׁתֵּ֣י תֹרִ֗ים אוֹ֮ לִשְׁנֵ֣י בְנֵי־יוֹנָה֒ וְהֵבִ֨יא אֶת־קָרְבָּנ֜וֹ אֲשֶׁ֣ר חָטָ֗א עֲשִׂירִ֧ת הָאֵפָ֛ה סֹ֖לֶת לְחַטָּ֑את לֹא־יָשִׂ֨ים עָלֶ֜יהָ שֶׁ֗מֶן וְלֹא־יִתֵּ֤ן עָלֶ֙יהָ֙ לְבֹנָ֔ה כִּ֥י חַטָּ֖את הִֽיא׃
만일 힘이 산비둘기 둘이나 집비둘기 둘에도 미치지 못하거든 그 범과를 인하여 고운 가루 에바 십분 일을 예물로 가져다가 속죄제물로 드리되 이는 속죄제인즉 그 위에 기름을 붓지 말며 유향을 놓지 말고
Sifra
1) (Vayikra 5:11) "And if his hand does not attain to two turtle-doves or to two young pigeons, then he shall bring his offering wherein he has sinned, a tenth of an ephah of fine flour for a sin-offering.": R. Yehudah says: Beloved is a mitzvah in its time. For he brings a tenth of an ephah immediately, and we do not wait for him until he becomes wealthy and brings a lamb or goat-kid.
Sifra
2) R. Eliezer says: Beloved is a mitzvah in its time. For in (the area of altar) valuations (arachin) he brings a sela immediately, and we do not wait for him until he becomes wealthy and brings fifty selaim.
Sifra
3) R. Shimon says: Beloved is a mitzvah in its time. For the fats (of the offerings) may be burned the entire night, and they override the Sabbath in their time, and we do not wait to burn them until the Sabbath has ended.
