The words translated as "plant" and "planted" have multiple meanings and do not really mean "plant" or "planted," except in the sense of planting trees, which is Jesus' analogy for families. Planted is a play on words. The word translated as "plant" means a given season's crops or a generation of people. It is used only here by Jesus. The word translated as "planted" means "engender" or "fathered." It is used only seven times. The word translated as "uprooted" is also rare, used only three times.
While Jesus often uses symbols or, as he says, figures of speech, this verse has several meanings right on the surface. Indeed, the KJV may pull the symbols out of a verse where the plain meaning is right on the surface.
