ציטירנדיקער פּירוש אויף משלי 6:18

Tremble (רִגְזוּ - rigzu): Because they shamed him instead of [giving him] his glory, and spoke falsehood concerning him [v. 3], he said: Tremble (Rigzu) out of [fear of] HaShem; fear (pachadu). Similar [is the usage of the root in (Genesis 45:24)]: "Do not tremble/quarrel (al tirg'zu) on the way." [The reason for fear is] because the king takes note of the mockery directed at him. And some say (v'yesh omrim): [That rigzu means "be angry," and the verse means:] Even if you think falsehood in your hearts, let it not come out of your mouths. But this is not correct (ve-zeh eineno nakhon). For it is written (Psalm 15:2): "who speaks truth in his heart," [and (Proverbs 6:18)]: "a heart that devises wicked thoughts (machshevot aven)." The speech of the heart is the essential thing (ha-ikkar), and the tongue is not, but rather [it is merely] an interpreter (melitz) between the heart and the hearers. Rather, the interpretation is: That you should think in your hearts at night upon your beds—when you have no involvement with other people—so that you will not speak falsehood during the day. And this [leads to the final phrase]: "And be silent/still. Selah" (וְדֹמּוּ סֶלָה - Ve-dommu selah).

The Hebrew word ḥ-m-d has two different meanings. One meaning is robbery, oppression, taking from others through force or compulsion (as in, “no man will attack your land” [Exodus 34: 24] — for if the verb denotes jealousy, then a verse intending to extol the land instead deprecates it!). The other meaning is jealousy, that does not express itself in overt action. “You shall not be jealous of your fellow-man’s house” [Exodus 20: 14] is the Ninth Commandment, and “you shall not be jealous of your fellow-man’s wife” [Exodus 20: 14] is the Tenth Commandment. Either “your fellow-man’s house” is part of the same Commandment as “your fellow-man’s wife”, or it is a separate principle in its own right. Here there is evidence for the latter: Moshe, explaining the Torah, in this book has replaced one instance of “you shall not be jealous” with “you shall not desire”. Many people have said that there is no sin in thinking something, and that thoughts carry neither reward nor punishment. I shall not go into the many proofs to the contrary at great length. Suffice to point out “The thoughts of the wicked are an abomination to God ” [Proverbs 15: 26], “You did well, insofar as it was your intention” [I Kings 8: 18], and “to those who are upright in their hearts” [Psalms 125: 4]. Moshe himself summed it all up when he said “to do it with your mouth and with your heart” [30: 14]. The core of all the commandments is the improvement of character — and the majority of them are essentially reminders [see comment on Leviticus 19: 19]. Moreover, the existence of a distinction between an intentional sin and an accidental sin is definitive proof.
