Sforno on Deuteronomy 33:24/ספורנו על דברים ל״ג:כ״ד

1ברוך מבנים אשר, Asher will enjoy an exceptional blessing, not shared by the other tribes. It is in the nature of things that wealthy people attract the jealousy of those who are not so blessed with wealth. Asher will not be subject of jealousy, but, on the contrary, will be well liked by all the other tribes.

2The reason is that he will sell the abundance of olive oil over which he disposes at low prices to his fellow tribes.
