OET interlinear 1 KI 1:36

uW Translation Notes:

Note 1 topic: figures-of-speech / exclamations

אָמֵ֑ן

amen

Benaiah is using a phrase that expresses a strong feeling of agreement with the king’s command and loyalty to him. There may be an equivalent word or phrase in your language that you can use in your translation to convey this feeling. If not, you could say what Benaiah was feeling, or you could say what made him agree so strongly. Alternate translation: [Yes, indeed!] or [I strongly agree!]

Note 2 topic: figures-of-speech / explicit

כֵּ֚ן יֹאמַ֣ר יְהוָ֔ה אֱלֹהֵ֖י אֲדֹנִ֥⁠י הַ⁠מֶּֽלֶךְ

(Some words not found in UHB: and,he_answered Bənā^yāh son_of Yəhōyādāˊ/(Jehoiada) DOM the=king and=he/it_said amen yes/correct/thus/so say YHWH god_of my=master the,king )

By say thus, Benaiah is not just wishing that Yahweh would say the same thing that David has just said. He is wishing that Yahweh would make this happen. You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [May Yahweh, the God of my lord the king, make this happen]
