Isaías 36:22 Halacá: Mishneh Torah, Foreign Worship and Customs

Whosoever hears the Name being blasphemed is obliged to rend his garments; even when an alias is used in blaspheming, if the reviler be an Israelite, he is obliged to rend his garments. He who hears the blasphemy direct or he who hears it from a witness, both, are obliged to rend their garments. But he who hears it from an idolater is not obliged to rend his garments. As for Eliakim and Shebnah¹¹See Second Kings, 18. 13-19.9; Isa. 36.1-37.37. G., they rent not their garment save because Rab-shakeh was a converted Israelite. All the judges and witnesses in a blasphemy case, successively put their hand upon the head of the blasphemer, each one saying to him: "Thy blood be upon thy head, thou alone hast brought it upon thyself". Of all upon whom a tribunal pronounces the sentence of death there is none upon whose head the hands of the judges and witnesses are put, save upon the blasphemer, even as it is said: "And let all that heard him lay their hands upon his head" (Lev. 24.14).¹²Sanhedrin, 60a; Sifra, Lev. 24.
