Komentaryo sa Deuteronomio 5:18: Rashi, Ibn Ezra, Ramban & Rabbeinu Bahya

ולא תתאוה — The Targum renders this by ולא תירוג which, too, is an expression denoting “desiring” (חמד the word used in the preceding part of this verse), just as (Genesis 2:9) “נחמד to the eyes”, we render in the Targum by “desirable (רגג) to behold”.

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.

He added an explanation in the commandment Neither shalt thou covet in that he mentioned first the [neighbor’s] wife [whereas in the Book of Exodus the neighbor’s house is stated first] for the imagination of man’s heart is evil from his youth¹⁷³Genesis 8:21. with respect to women more than anything else. He further explained, that included in the term “coveting” is even mere “desire” [as stated here, Neither shalt thou ‘desire’ thy neighbor’s house etc.]. Thus if he desires to rob anything from his neighbor, but is unable to do so because his neighbor is stronger than he, or because in his locality there is fear of the government, he transgresses this commandment.¹⁷⁴Thus, if a person really desires something but does nothing to obtain it, he transgresses the prohibition, neither shalt thou desire. If his desire for the object is so strong that he obtains it through some scheme, he additionally transgresses the commandment, Thou shalt not covet. But if the owner refuses under all circumstances to sell it and he takes it by force, he also transgresses the commandment, Nor shalt thou rob him (Leviticus 19:13). See “The Commandments,” Vol. II, pp. 251-252. He added here his field, wherefrom the Rabbis have interpreted in the Mechilta:¹⁷⁵Mechilta, Yithro 5. “Perhaps I may reason: Just as the specific examples [mentioned in the Decalogue in Exodus, namely, his manservant, his maidservant, his ox, or his ass] are movable property which may not be seized from customers in case of non-payment by the creditor, so also, I can include [in the prohibition not to covet] only movable property which may not be resorted to for non-payment. But when it says in Deuteronomy his field [which is immovable property and may be resorted to for non-payment] you must perforce interpret the verse as follows: Just as the specific matters deal with things one can buy and sell, so all things one can buy and sell [are included in this prohibition].”
