(Devarim, Ibid. 23) "And of Naftali he said": Why is this written? Because it is written (Bereshith 47:2, see above ["And of Gad he said"]).
"Naftali sates the desire": We are hereby taught Naftali was happy in his portion: in seas, in fish, and in date-berries.
"and it is full of the blessing of the L-rd": the Ginnosar valley. Rebbi says: This is the house of study of Tiberias, concerning which it is written (Psalms 145:19) "The will of those who fear Him shall He do."
"the sea": the sea of Sivchi and the sea of Tiberias. "and the south": whereby we are taught that he was given a full rope-measure (of fishing net) in the south.
