Charles Spurgeon Commentary Genesis 49:21

"Naphtali is a hind let loose: He giveth goodly words." — Genesis 49:21 (ASV)

He gives goodly words.

He has liberty in speech, freedom of utterance, he is not in bonds, he is as a hind let loose.

Naphtali is a hind let loose:

The type of what a Christian minister should be—indeed, what every Christian worker should be—a hind let loose, one who can say with David, O Lord, truly I am thy servant; I am thy servant, and the son of thine handmaid. Thou hast loosed my bonds.

Naphtali is a hind let loose: he giveth goodly words.

Naphtali was a tribe notable for those that could speak freely, helped by God with a holy freedom in bearing testimony to his truth.
