Genesis 49:20 - Joseph Benson’s Commentary on the Old and New Testaments

Out of Asher his bread shall be fat This implies that it should be a rich tribe, replenished not only with bread for necessity, but with fatness, with dainties, royal dainties, and these exported out of Asher to other tribes, perhaps to other lands. The God of nature has provided for us not only necessaries but dainties, that we might call him a bountiful benefactor; yet, whereas all places are competently furnished with necessaries, only some places afford dainties. Corn is more common than spices. Were the supports of luxury as universal as the supports of life, the world, in consequence of the wickedness of man, would be worse than it is, and surely it is bad enough.
