OET interlinear 1 KI 8:15

uW Translation Notes:

Note 1 topic: figures-of-speech / activepassive

בָּר֤וּךְ יְהוָה֙

(Some words not found in UHB: and=he/it_said blessed YHWH god_of Yisrael which/who he/it_had_said with,mouth_of,his DOM Dāvid father_of,my and,with,hand_of,his fulfilled to=say )

See how you translated the similar expression in 1:48. Alternate translation: [May people bless Yahweh] or [May people praise Yahweh]

Note 2 topic: figures-of-speech / infostructure

אֲשֶׁר֙ דִּבֶּ֣ר בְּ⁠פִ֔י⁠ו אֵ֖ת דָּוִ֣ד אָבִ֑⁠י וּ⁠בְ⁠יָד֥⁠וֹ מִלֵּ֖א

(Some words not found in UHB: and=he/it_said blessed YHWH god_of Yisrael which/who he/it_had_said with,mouth_of,his DOM Dāvid father_of,my and,with,hand_of,his fulfilled to=say )

If it would be more natural in your language, you may want to put the information that Yahweh has now fulfilled something by his hand before the information that this was something he spoke by his mouth. Alternate translation: [who has fulfilled by his hand what he spoke by his mouth to David my father]

Note 3 topic: figures-of-speech / metonymy

וּ⁠בְ⁠יָד֥⁠וֹ מִלֵּ֖א

and,with,hand_of,his (Some words not found in UHB: and=he/it_said blessed YHWH god_of Yisrael which/who he/it_had_said with,mouth_of,his DOM Dāvid father_of,my and,with,hand_of,his fulfilled to=say )

Here, hand represents the power of a person. If it would be helpful in your language, you could use an equivalent expression or state the meaning plainly. Alternate translation: [and fulfilled by his own action]
