uW Translation Notes:

Note 1 topic: figures-of-speech / metonymy

יֵאָ֤מֶן נָא֙ דְּבָ֣רְךָ֔ אֲשֶׁ֣ר דִּבַּ֔רְתָּ לְ⁠עַבְדְּ⁠ךָ֖ דָּוִ֥ד אָבִֽ⁠י

confirmed now (Some words not found in UHB: and=now god_of Yisrael confirmed now דברי,ך which/who promised to,servant_of,your Dāvid father_of,my )

Solomon is using the term word to represent what God said by using words. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: [may what you said when you spoke to your servant David, my father, please be confirmed]

Note 2 topic: figures-of-speech / activepassive

יֵאָ֤מֶן נָא֙ דְּבָ֣רְךָ֔ אֲשֶׁ֣ר דִּבַּ֔רְתָּ

confirmed now (Some words not found in UHB: and=now god_of Yisrael confirmed now דברי,ך which/who promised to,servant_of,your Dāvid father_of,my )

The expression may … be confirmed is a passive verbal form. If your language would not use that form, you could express the idea in active form or in another way that is natural in your language. Alternate translation: [please confirm your word that you spoke] or [please confirm what you said when you spoke]
