Deuteronomy 5:21

(21) His field.—These words are not found in Exodus 20:0. The children of Israel had now become, or were just about to become, landowners; hence the addition is appropriate in this place. There is also another slight verbal alteration. One word only is used for “covet” in Exodus 20:17; here two are employed. The idea of the one is to “delight in,” and the other to “lust after.”
