Leviticus 20:4

וְאֶל־בְּנֵי יִשְׂרָאֵל תֹּאמַר אִישׁ אִישׁ מִבְּנֵי יִשְׂרָאֵל וּמִן־הַגֵּר הַגָּר בְּיִשְׂרָאֵל אֲשֶׁר יִתֵּן מִזַּרְעוֹ לַמֹּלֶךְ מוֹת יוּמָת עַם הָאָרֶץ יִרְגְּמֻהוּ בָאָֽבֶן

Moreover, thou shalt say to the children of Israel: Whosoever he be of the children of Israel, or of the strangers that sojourn in Israel, that giveth of his seed unto Molech; he shall surely be put to death; the people of the land shall stone him with stones.

וַאֲנִי אֶתֵּן אֶת־פָּנַי בָּאִישׁ הַהוּא וְהִכְרַתִּי אֹתוֹ מִקֶּרֶב עַמּוֹ כִּי מִזַּרְעוֹ נָתַן לַמֹּלֶךְ לְמַעַן טַמֵּא אֶת־מִקְדָּשִׁי וּלְחַלֵּל אֶת־שֵׁם קָדְשִֽׁי

I also will set My face against that man, and will cut him off from among his people, because he hath given of his seed unto Molech, to defile My sanctuary, and to profane My holy name.

וְשַׂמְתִּי אֲנִי אֶת־פָּנַי בָּאִישׁ הַהוּא וּבְמִשְׁפַּחְתּוֹ וְהִכְרַתִּי אֹתוֹ וְאֵת כָּל־הַזֹּנִים אַחֲרָיו לִזְנוֹת אַחֲרֵי הַמֹּלֶךְ מִקֶּרֶב עַמָּֽם

then I will set My face against that man, and against his family, and will cut him off, and all that go astray after him, to go astray after Molech, from among their people.

וְהַנֶּפֶשׁ אֲשֶׁר תִּפְנֶה אֶל־הָֽאֹבֹת וְאֶל־הַיִּדְּעֹנִים לִזְנוֹת אַחֲרֵיהֶם וְנָתַתִּי אֶת־פָּנַי בַּנֶּפֶשׁ הַהִוא וְהִכְרַתִּי אֹתוֹ מִקֶּרֶב עַמּֽוֹ

And the soul that turneth unto the ghosts, and unto the familiar spirits, to go astray after them, I will even set My face against that soul, and will cut him off from among his people.
