Rashi
שבע רצון [NAPHTALI IS] SATISFIED WITH DESIRE — it means that his land was full of everything that its inhabitants could desire.
Chizkuni
שבע רצון, Naftaly is satisfied, aware of having been favoured;” the fruit of his orchards is not only of the highest quality, but also ripens ahead of those in other regions of the land. Whenever he tastes them he is gratefully conscious of his good fortune.
Da'at Zekenim
נפתלי שבע רצון, “Naftaly is sated with favour;” its territory produced fruit that ripened earlier than that of the other tribes. According to our author, fruit that ripens early in the season is more satisfying than fruit ripening later in the season. The psychology behind this is explained by the author as the farmer having had to anxiously wait full of desire until he could satisfy his longing.
