OET interlinear PSA 31:18

uW Translation Notes:

Note 1 topic: figures-of-speech / activepassive

תֵּ֥אָלַ֗מְנָה שִׂפְתֵ֫י שָׁ֥קֶר

(Some words not found in UHB: YHWH not put_to_shame that/for/because/then/when I,have_called_out_to_you put_to_shame wicked go_dumbfounded to,Sheol )

The expression Let lying lips be silenced is a passive verbal form. If it would be unnatural to use that form, you could express the idea in active form or in another way that is natural in your language. If you need to say who does the action, the context indicates that it is God. Alternate translation: [May God silence lying lips] or [May lying lips become silent]

Note 2 topic: figures-of-speech / metonymy

שִׂפְתֵ֫י שָׁ֥קֶר

(Some words not found in UHB: YHWH not put_to_shame that/for/because/then/when I,have_called_out_to_you put_to_shame wicked go_dumbfounded to,Sheol )

Here, lying lips represents people who tell lies. If it would be helpful in your language, you could use an equivalent expression or state the meaning plainly. Alternate translation: [those who lie]

Note 3 topic: figures-of-speech / nominaladj

צַדִּ֥יק

(Some words not found in UHB: YHWH not put_to_shame that/for/because/then/when I,have_called_out_to_you put_to_shame wicked go_dumbfounded to,Sheol )

David is using the adjective righteous as a noun to mean a certain kind of person. Your language may use adjectives in the same way. If not, you can translate this adjective with an equivalent phrase as in the UST.

Note 4 topic: figures-of-speech / abstractnouns

בְּ⁠גַאֲוָ֥ה וָ⁠בֽוּז

(Some words not found in UHB: YHWH not put_to_shame that/for/because/then/when I,have_called_out_to_you put_to_shame wicked go_dumbfounded to,Sheol )

If your language does not use abstract nouns for the ideas of pride and contempt, you could express the same ideas in other ways. Alternate translation: [proudly and contemptuously] or [in a proud and contemptuous manner]

Note 5 topic: figures-of-speech / doublet

בְּ⁠גַאֲוָ֥ה וָ⁠בֽוּז

(Some words not found in UHB: YHWH not put_to_shame that/for/because/then/when I,have_called_out_to_you put_to_shame wicked go_dumbfounded to,Sheol )

The terms pride and contempt mean similar things. David is using the two terms together for emphasis. If it would be clearer for your readers, you could express the emphasis with a single phrase. Alternate translation: [with great arrogance]
