Chasidut for Leviticus 20:2
וְאֶל־בְּנֵ֣י יִשְׂרָאֵ֘ל תֹּאמַר֒ אִ֣ישׁ אִישׁ֩ מִבְּנֵ֨י יִשְׂרָאֵ֜ל וּמִן־הַגֵּ֣ר ׀ הַגָּ֣ר בְּיִשְׂרָאֵ֗ל אֲשֶׁ֨ר יִתֵּ֧ן מִזַּרְע֛וֹ לַמֹּ֖לֶךְ מ֣וֹת יוּמָ֑ת עַ֥ם הָאָ֖רֶץ יִרְגְּמֻ֥הוּ 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.
Chayei Moharan
On the subject of wars between nations and needless bloodshed, the Rebbe said, “Many of the misguided follies which people in previous eras believed in, such as primitive cults like child-sacrifice to Molekh (Leviticus 20:2) and so on, have now disappeared. But so far, the pursuit of war—misguided error that it is—has not been abolished.” The Rebbe had contempt for the scientists who developed new weapons, saying, “What great sages they must be to figure out how to make a wonderful weapon that can kill thousands of people at once! Is there anything more foolish than to kill so many people for nothing!”
