A.T. Robertson Commentary Revelation 14:7

"and he saith with a great voice, Fear God, and give him glory; for the hour of his judgment is come: and worship him that made the heaven and the earth and sea and fountains of waters." — Revelation 14:7 (ASV)

And he saith (λεγων). See above.

Fear God (φοβηθητε τον θεον). First aorist passive (deponent) imperative of φοβεομα, here transitive with the accusative as in Lu 12:5. It is a call to judgment with no hope offered except by implication (Acts 14:15ff.).

Give him glory (δοτε αυτω δοξαν). Second aorist active indicative of διδωμ. For the phrase see 11:13.

The hour is come (η ωρα ηλθεν). Second aorist (prophetic use) active indicative of ερχομα. Common idiom in John's Gospel (2:4; 4:21,23; 5:25,28; 7:30, etc.).

Worship (προσκυνησατε). First aorist active imperative of προσκυνεω with the dative case. Solemn call to the pagan world to worship God as Creator (4:11; 10:6), as in Ps 96:6; Acts 14:15. For "the fountains of waters" see 8:10.
