Jacob speaks about the descendants of Naphtali as if they were a female deer that is free to run. This may emphasize that they will be swift messengers. AT: "The descendants of Naphtali will be like deer set free" (See: [[rc://en/ta/man/translate/figs-metaphor]])
A "fawn" is a baby deer. The meaning of the Hebrew word is unclear. Some versions translate it as "have beautiful words" or "speak beautiful things" (See: [[rc://en/ta/man/translate/figs-metaphor]])
