OET interlinear PSA 108:1

uW Translation Notes:

Note 1 topic: figures-of-speech / metaphor

נָכ֣וֹן לִבִּ֣⁠י

(Some words not found in UHB: song song of,David )

Here David is speaking as if his heart were something that could be made steadfast. He means that he has become determined and committed to praising God. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [I have made myself steadfast]

Note 2 topic: figures-of-speech / activepassive

נָכ֣וֹן לִבִּ֣⁠י

(Some words not found in UHB: song song of,David )

The expression My heart is made steadfast 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. Alternate translation: [I have made my heart steadfast]

Note 3 topic: translate-alternativereadings

אַף־כְּבוֹדִֽ⁠י

(Some words not found in UHB: song song of,David )

The word translated as glory could be: (1) a reference to all of David’s strength. Alternate translation: [indeed, with all that I am] or (2) translated as the very similar word for “liver.” In this case, it would be understood as functioning very much like heart in the first part of the verse, and also stand for the place in the body where a person’s will and emotions are. Either way you translate it, the meaning is very similar. Alternate translation: [indeed, with my liver] or [indeed, with my entire will]
