On the banks of the future river that will flow from the sanctuary, trees will grow, of which it is said, “The fruit thereof shall be for meat, and the leaf thereof for medicine” (Ezek. 47:12). This agrees with Revelation 22:2. The prophet Jeremiah twice observes that when God brings His judgments upon a people, no medicine will cure them (Jer. 30:13; Jer. 46:11). Proverbs 17:22 Says, “A merry heart doeth good like a medicine,” or “promoteth healing.”
