יֹֽצְרֵי־פֶ֤סֶל כֻּלָּם֙ תֹּ֔הוּ וַחֲמוּדֵיהֶ֖ם בַּל־יוֹעִ֑ילוּ וְעֵדֵיהֶ֣ם הֵׄ֗מָּׄהׄ בַּל־יִרְא֛וּ וּבַל־יֵדְע֖וּ לְמַ֥עַן יֵבֹֽשׁוּ׃
They that fashion a graven image are all of them vanity, And their delectable things shall not profit; And their own witnesses see not, nor know; That they may be ashamed.
Mishnah Avodah Zarah
On the three days preceding the festivals of idolaters, it is forbidden to conduct business with them, to lend articles to them or borrow from them, to lend or borrow any money from them, to repay a debt, or receive repayment from them. Rabbi Judah says: we should receive repayment from them, as this can only depress them; But they [the Rabbis] said to him: even though it is depressing at the time, they are glad of it subsequently.
