Rashi on Deuteronomy 5:18/רש"י על דברים ה׳:י״ח

1ולא 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”.
