Commentary for Numbers 7:78

אחירע בן עינן. This name appears to contain an allusion to the statement of the Sifri on Deut. 33,23 that Naftali was satisfied with favour, i.e. that he did not strive for more than had been granted to him. He enjoyed the fruits of Ginnosaur, the fish of the lake of Kinneret, etc. The word אחי רע suggests that in Naftali's eyes his brothers had received a share inferior to his. His "eye," i.e. his aspirations had been fully met by the blessing he received at the hands of Moses.
