וְכֵן אָסוּר לְצַיֵר צוּרַת אָדָם. וַאֲפִלּוּ רַק פַּרְצוּף פְּנֵי אָדָם לְחוּד, נַמִּי אָסוּר. וַאֲפִלּוּ לְהַשְׁהוֹתָהּ, אָסוּר, עַד שֶׁיְקַלְקֵל אוֹתָה קְצָת. וְדַוְקָא בְּצוּרָה שְׁלֵמָה, דְּהַיְנוּ בִּשְׁתֵּי עֵינַיִם וְחֹטֶם שָׁלֵם. אֲבָל אִם אֵינָהּ רַק חֲצִי הַצוּרָה מִצַד אֶחָד, כְּדֶרֶךְ קְצָת הַמְצַיְרִים צַד אֶחָד שֶׁל הַצּוּרָה, זֶה אֵינוֹ אָסוּר.
It is also forbidden to sculpture the image of a person. It is prohibited to sculpture even the face of a person, and it is even forbidden to keep it in your house, unless you disfigure it to some extent. However, only a full face is forbidden, that is, when it has two eyes and a complete nose, but if it is only half a face, a profile, like some artists who form one side of the (picture) face, it is not forbidden.

If a ring has a seal on it, consisting of a person's image, and the image was made in relief, you are forbidden to keep it; but it is permissible to seal with it because then the signature becomes depressed. If the image on the ring is depressed, you may keep the ring, but you are forbidden to seal with it, because it comes out in relief.

It is forbidden to gaze at the image of a person, for it is called a pessel (idol), and this is in violation of the Scripture, "Do not turn to idols." However, with regard to the images on coins, since everyone is accustomed to them, it is permitted. A very pious person is even careful about this.
