Et au sujet d’Asher, il dit: "Béni entre les fils soit Asher! Bienvenu auprès de ses frères, et baignant son pied dans l’huile.
Rashi
ברוך מבנים אשר LET ASHER BE BLESSED AMONG SONS (or, “on account of sons”) — I have found in the Sifrei Devarim 355:19 the following: You will find none of the tribes who was so blessed with children as Asher, but I do not know how this was so.
Chizkuni
ברך מבנים אשר, “Asher be blessed more than the other sons (of Yaakov).” He receives these blessings from the other tribes, as proved from the end of this verse.
Da'at Zekenim
ברוך מבנים אשר, “Asher is blessed more than the other sons.” The reason for this is that all the other tribes also bless the tribe of Asher, as we know from the words יהי רצוי אחיו, “let him be favoured by his brethren.” (our verse) Moses goes on to explain the reason for this when he says: וטובל בשמן רגלו, “and let him dip his foot in oil.” His territory is so full of oil (from his olive groves) that it provides a surfeit for all the other tribes. Rabbi Eliyahu the priest, quoting his uncle, Rabbi Moshe, points out that tin the latest census the numbers for the tribe of Asher were 30% higher than in the previous census. Seeing that the total number of army aged males had practically not changed over 39 years, this is most remarkable, and the reason why Moses describes that tribe as more blessed than any of the others. (Compare Numbers 1,41 and Numbers 26,47)
