John Gill Reformed Baptist @doctorgill

Or "doctrine" (n); the doctrine of those who are taught by the word, and are wise unto salvation; the words or doctrines of the wise, which are given forth by one Shepherd; the instructions of such who are like Scribes, well instructed themselves unto the kingdom of heaven: these are as a fountain of living...

(Compare Pro 10:11). fountain--or, "source of life." to depart--(compare Pro 1:2-4), or, "for departing," &c., and so gives life.
