Isa. i. 8.  ὀπωροφυλάκιον is the hut of the watchman who guarded the crop when ripening for harvest.  Σικυήλατον is explained by Basil in his comment on the passage of Isaiah as “A place that produces quick-growing and perishable fruits.”  This agrees with the etymological sense of the word as “a forcing-bed for cucumbers” (Hippocrates apud Fritzsche, “Der Brief des Jeremia,” v. 70).  On the form σικυηράτῳ, see the notes on the Epistle of Jeremy in the Speaker’s Commentary.
