30. oak—Ye shall be like the "oaks," the object of your "desire" (Isa 1:29). People become like the gods they worship; they never rise above their level (Ps 135:18). So men's sins become their own scourges (Jer 2:9). The leaf of the idol oak fades by a law of necessary consequence, having no living sap or "water" from God. So "garden" answers to "gardens" (Isa 1:29).
