Midrasch zu Wajikra 19:16

(Lev. 19:2:) “Speak unto the whole congregation of the Children of Israel, and say unto them, ‘You shall be holy.’” What reason did He have to speak this parashah in an assembly?⁵ Lev. 7:3; Lev. R. 24:5. Why did He not say, “Speak unto the Children of Israel,” as in the rest of the parashiot,⁶I.e., in Exod. 14:2, 15; 25:2; 31:13 Lev. 1:2; 4:2; 7:23, 29; 12:2; 15:2; 18:2; 23:2, 10, 24, 34; 25:2; 27:2; Numb. 5:6, 12; 6:2; 9:10; 15:2, 18, 38; 17:17; 19:2; 33:51; 35:10. rather than “[Speak] unto the whole congregation of the Children of Israel?” Because all of the [ten] commandments are included within it. How? In the commandments it is written (in Exod. 20:2 = Deut. 5:6), “I [am] the Lord your God”; and here (in Lev. 19:2), “I [am] the Lord your God.” In the commandments it is written (in Exod. 20:3 = Deut. 5:7), “You shall have no [other gods beside Me]”; and here (in Lev. 19:4), “Do not turn unto idols.” In the commandments it is written (in Exod. 20:7 = Deut. 5:11), “You shall not take [the name of the Lord your God in vain]”; and here (in Lev. 19:12), “You shall not swear falsely by My name.” In the commandments it is written (Deut. 5:12), “Guard the Sabbath day”; and here it is written (in Lev. 19:3), “You shall keep My Sabbaths.” In the commandments it is written (in Exod. 20:12 = Deut. 5:16), “Honor your father and your mother”; and here it is written (in Lev. 19:3, cont.), “you each shall fear his mother and his father.” In the commandments it is written (in Exod. 20:13 = Deut. 5:17), “You shall not murder”; and here it is written (in Lev. 19:16), “you shall not stand over the blood of your neighbor.” in the commandments it is written (in Exod. 20:13 = Deut. 5:17), “you shall not commit adultery”; and here it is written (in Lev. 19:2), “You shall be holy.“ In the commandments it is written (in Exod. 20:13 = Deut. 5:17), “you shall not stea”l; and here it is written (in Lev. 19:11), “You shall not steal.” In the commandments it is written (in Exod. 20:13 = Deut. 5:17), “you shall not bear [false witness against your neighbor]”; and here it is written (in Lev. 19:16), “You shall not go around as a slanderer among your people.” In the commandments it is written (in Exod. 20:14 = Deut. 5:18), “You shall not covet”; and here it is written (in Lev. 19:13), “You shall not oppress your neighbor, and you shall not rob him.” Here all of the [ten] commandments are included within [it]. It is therefore stated (in Lev. 19:2), “Speak unto the whole congregation [of the Children of Israel].”

(Fol. 31) Our Rabbis were taught: "Whence do we know that one of the judges, when leaving court, must not say: 'I was in favor of the defendant, but my colleagues were against me, and I could not help it, for they were in the majority?' The passage, therefore reads (Lev. 19, 16) Thou shalt not go up and down as a tale-bearer among thy people. And another passage says (Prov. 11, 13) He that walketh about as a tale-bearer revealeth secrets." There was a disciple concerning whom there was a rumor that after twenty-two years he disclosed a secret thing which was taught in the college. R. Ami drove him out of the college, and announced: "This man is a revealer of secrets."
