OET interlinear REV 3:7

uW Translation Notes:

Note 1 topic: figures-of-speech / nominaladj

ὁ Ἅγιος, ὁ Ἀληθινός

the Holy_‹One› the True_‹One›

Jesus is using the adjectives Holy and True as nouns to describe himself as a certain kind of person. Your language may use adjectives in the same way. If not, you can translate these words with equivalent phrases, as the ULT does by adding the word One in each case.

Note 2 topic: figures-of-speech / metaphor

ὁ ἔχων τὴν κλεῖν Δαυείδ

the the ¬which having the key the_‹one› (Some words not found in SR-GNT: καὶ τῷ ἀγγέλῳ τῆς ἐν Φιλαδελφείᾳ ἐκκλησίας γράψον τάδε λέγει ὁ Ἅγιος ὁ Ἀληθινός ὁ ἔχων τὴν κλεῖν Δαυίδ ὁ ἀνοίγων καὶ οὐδεὶς κλείσει καὶ κλείων καὶ οὐδεὶς ἀνοίγει)

Jesus is not referring to a literal key. Rather, he is quoting from Isaiah 22:22, where God says that he will make a man named Eliakim the administrator of the royal palace in Jerusalem and give him the “key of the house of David,” symbolizing authority over the kingdom that the dynasty of David rules. As the Messiah, Jesus now has David’s royal authority. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: “the one having royal authority as the Messiah”

Note 3 topic: figures-of-speech / parallelism

ὁ ἀνοίγων καὶ οὐδεὶς κλείσει, καὶ κλείων καὶ οὐδεὶς ἀνοίγει

the the ¬which the_‹one› opening_up and no_one /will_be/_shutting and shutting and no_one /is/_opening_up

This is a continuation of the quotation and the image of the key from Isaiah 22:22. These two phrases say the same thing in opposite ways. God, speaking through Isaiah, was using repetition to emphasize the idea that the phrases express, that he would give this new palace administrator authority that no one could defy. If it would be helpful to your readers, you could combine the phrases or express their meaning plainly. Alternate translation: “who decides definitively whether to open a door or to lock it shut” or “whose authority no one can defy”
