Albert Barnes Commentary Deuteronomy 33:23

"And of Naphtali he said, O Naphtali, satisfied with favor, And full with the blessing of Jehovah, Possess thou the west and the south." — Deuteronomy 33:23 (ASV)

Satisfied with favor - Compare Genesis 49:21 and note.

The west and the south - that is, taking the words as referring not to geographical position but to natural characteristics, “the sea and the sunny district.” The possession of Naphtali included nearly the whole west coast of the Sea of Galilee, the Lake of Merom (the modern Bahr el Huleh), and the well-watered district near the springs of Jordan. It contained some of the grandest scenery and some of the most fertile land in Palestine.

Josephus speaks of the shore of Gennesaret as “an earthly paradise;” and Porter describes it as “the garden of Palestine.” The modern name for this district, “land of good tidings,” is significant.
