Ma'aser Sheini 1:7
Ma'aser Sheini1: 7
אֵין לוֹקְחִין עֲבָדִים וּשְׁפָחוֹת וְקַרְקָעוֹת וּבְהֵמָה טְמֵאָה מִדְּמֵי מַעֲשֵׂר שֵׁנִי; וְאִם לָקַח, יֹאכַל כְּנֶגְדָּן. אֵין מְבִיאִין קִנֵּי זָבִים וְקִנֵּי זָבוֹת וְקִנֵּי יוֹלְדוֹת, חַטָּאוֹת וַאֲשָׁמוֹת מִדְּמֵי מַעֲשֵׂר שֵׁנִי; וְאִם הֵבִיא, יֹאכַל כְּנֶגְדָּם. זֶה הַכְּלָל: כֹּל שֶׁהוּא חוּץ לַאֲכִילָה וְלִשְׁתִיָּה וּלְסִיכָה מִדְּמֵי מַעֲשֵׂר שֵׁנִי, יֹאכַל כְּנֶגְדּוֹ.
One may not buy slaves, maidservants, lands, or nonkosher animals from maaser sheni funds; and if he bought [one of these items], he must eat their equivalence. One may not bring the bird-offerings of a zav, or the bird-offerings of a zavah, or the bird-offerings of a woman after childbirth, or chatas-offerings, or asham-offerings, from funds of maaser sheni; and if he brought [of these offerings], he must eat their equivalence. This is the general principle: [If] anything that is outside of eating, drinking, or anointing is [acquired] from maaser sheni funds, he must eat its equivalence.
