Йешайау 8:21 Галаха: Mishneh Torah, Foreign Worship and Customs

וְעָ֥בַר בָּ֖הּ נִקְשֶׁ֣ה וְרָעֵ֑ב וְהָיָ֨ה כִֽי־יִרְעַ֜ב וְהִתְקַצַּ֗ף וְקִלֵּ֧ל בְּמַלְכּ֛וֹ וּבֵאלֹהָ֖יו וּפָנָ֥ה לְמָֽעְלָה׃

И они пройдут этот путь больным и голодным; И будет так, что, когда они будут голодны, они будут раздражать себя и проклинать своим царем и своим Богом, и, если они повернут свои лица вверх,

Mishneh Torah, Foreign Worship and Customs of the Nations

How does the idolater nullify it? If he cut off the tip of its nose, the tip of its ear, the first joint of its finger, or if he squeezed in its face though he diminished it not, or if he sold it to a goldsmith who is an Israelite, such are acts of nullification. But if he pawned it, or sold it to an idolater, or to an Israelite who is not a goldsmith, or if debris fell upon it and he did not clean it, or if robbers stole it and he made no effort to recover it; if he expectorated before it, or micturated before it; dragged it, or cast feces at it, such are not acts of nullification.13Ibid. 53a.
