DEUT186 It is a negative commandment not to crave in one’s heart something that belongs to his fellow-man as Scripture says, Neither shall you crave, etc. (D’varim 5:18). This prohibition is apart from the injunction, You shall not covet (Sh’moth 20:14). For a person transgresses the prohibition against craving once he thinks in his heart how he can acquire that object, and his heart is persuaded in the matter [to follow his plan]. Then he violates the injunction, Neither shall you crave, since craving is but in the heart alone. If he then acquires that object, having importuned its owner and sent many friends to him, until he gets it, he violates also the injunction, You shall not covet.
