OET interlinear HEB 7:17

uW Translation Notes:

Note 1 topic: grammar-connect-logic-result

γὰρ

(Some words not found in SR-GNT: μαρτυρεῖται Γάρ ὅτι Σύ ἱερεύς εἰς τόν αἰῶνα κατά τήν τάξιν Μελχισέδεκ)

The word For introduces the evidence or proof that Jesus has become a priest “according to the power of an indestructible life” (See: 7:16). If it would be helpful in your language, you could use a word or phrase that introduces evidence or proof. Alternate translation: [You know that is true because]

Note 2 topic: figures-of-speech / activepassive

μαρτυρεῖται

˱it˲_˓is_being˒_testified

If your language does not use the passive form in this way, you could express the idea in active form or in another way that is natural in your language. The author uses the passive form here to focus on what is testified rather than on who or what does the testifying. If you must state who did the action, the author implies that God did it when he spoke Psalm 110:4. Alternate translation: [God is testifying] or [the psalm is testifying]

Note 3 topic: writing-quotations

μαρτυρεῖται

˱it˲_˓is_being˒_testified

The author quotes from the Old Testament Scriptures. He does not introduce the words as a quotation but instead introduces them as something that has been testified. However, the audience would have understood that these were words from the Old Testament, specifically from Psalm 110:4. If your readers would not know that the quotation is from the Old Testament, you could include a footnote or use some other form to identify it. Alternate translation: [it is being testified in the Scriptures]

σὺ ἱερεὺς εἰς τὸν αἰῶνα κατὰ τὴν τάξιν Μελχισέδεκ

(Some words not found in SR-GNT: μαρτυρεῖται Γάρ ὅτι Σύ ἱερεύς εἰς τόν αἰῶνα κατά τήν τάξιν Μελχισέδεκ)

Since the author repeats here the same words that he quoted in 5:6, you should translate these words in exactly the same way as you did in that verse.
