OET interlinear PSA 89:38

uW Translation Notes:

Note 1 topic: writing-pronouns

וְ⁠אַתָּ֣ה זָ֭נַחְתָּ

(Some words not found in UHB: like_[the],moon established forever and,a_witness in,cloud[s] faithful selah )

Ethan is stating the pronoun you separately, even though the verb already includes this meaning. He is doing that to emphasize the sharp contrast between God’s promises and his present actions. If a speaker of your language would use an explicit pronoun for the same purpose, you may want to use that construction in your translation. If not, your language may have other ways of showing the meaning here. Alternate translation: [But you yourself have rejected]

Note 2 topic: grammar-connect-logic-contrast

וְ⁠אַתָּ֣ה זָ֭נַחְתָּ

(Some words not found in UHB: like_[the],moon established forever and,a_witness in,cloud[s] faithful selah )

Ethan uses the word But here to indicate a contrast between God’s covenant promises in the previous verses and his present treatment of the anointed king. In your translation, indicate this contrast in a way that is natural in your language.

Note 3 topic: figures-of-speech / doublet

זָ֭נַחְתָּ וַ⁠תִּמְאָ֑ס

(Some words not found in UHB: like_[the],moon established forever and,a_witness in,cloud[s] faithful selah )

The terms rejected and spurned mean similar things. Ethan 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: [you have completely rejected]
