"The physician who has laid a foundation for his professional knowledge by actual service in the sickroom will have a quickness of insight, an all-around knowledge, and an ability in emergencies to render needed service—all essential qualifications, which only a practical training can so fully impart. Ed 220.3"
"A wise man will hear, and will increase learning; and a man of understanding shall attain unto wise counsels:"
Both passages emphasize the importance of learning and gaining understanding. EGW focuses on practical experience for physicians, while Proverbs speaks more generally about increasing learning and attaining wise counsel. The connection is thematic, though somewhat broad.
