Sifrei Mitzvot sur Le Deutéronome 13:7

כִּ֣י יְסִֽיתְךָ֡ אָחִ֣יךָ בֶן־אִ֠מֶּךָ אֽוֹ־בִנְךָ֨ אֽוֹ־בִתְּךָ֜ א֣וֹ ׀ אֵ֣שֶׁת חֵיקֶ֗ךָ א֧וֹ רֵֽעֲךָ֛ אֲשֶׁ֥ר כְּנַפְשְׁךָ֖ בַּסֵּ֣תֶר לֵאמֹ֑ר נֵֽלְכָ֗ה וְנַֽעַבְדָה֙ אֱלֹהִ֣ים אֲחֵרִ֔ים אֲשֶׁר֙ לֹ֣א יָדַ֔עְתָּ אַתָּ֖ה וַאֲבֹתֶֽיךָ׃

Si ton frère, l’enfant de ta mère, si ton fils ou ta fille, ta compagne ou l’ami de ton cœur vient secrètement te séduire, en disant: "Allons servir des dieux étrangers," que toi ni tes pères n’avez jamais connus,

Sefer HaMitzvot

That we have been prohibited from inciting. And that is that one preach to an individual Jew to worship an idol. And this is called an enticer (mesit), as was previously explained. And the language of the prohibition of this is, "and they will not continue to do like this evil thing" (Deuteronomy 13:12). And one who transgressed this negative commandment is liable for stoning, as appears in the verse, "But rather surely kill him" (Deuteronomy 13:10). And the person that the inciter is trying to incite is the appropriate [one] to kill him - as He, may He be exalted, explains, "let your hand be the first against him." And the language of the Sifrei is, "This commandment is with the hand of the incited." And the regulations of this commandment have already been explained in Sanhedrin. (See Parashat Re'eh; Mishneh Torah, Foreign Worship and Customs of the Nations 5.)
