OET interlinear PSA 89:21

uW Translation Notes:

Note 1 topic: figures-of-speech / activepassive

יָ֭דִ⁠י תִּכּ֣וֹן

(Some words not found in UHB: found Dāvid servant_of,my with,the_oil_of my_holiness_of,my I,have_anointed_him )

The expression my hand will be established is a passive verbal form. If it would be unnatural to use that form, you could express the idea in active form. If you need to say who does the action, the context indicates that it is God. Alternate translation: [I will establish my hand]

Note 2 topic: figures-of-speech / metonymy

יָ֭דִ⁠י תִּכּ֣וֹן

(Some words not found in UHB: found Dāvid servant_of,my with,the_oil_of my_holiness_of,my I,have_anointed_him )

Here, hand represents the power or dominion of a person. If it would be helpful in your language, you could use an equivalent expression or state the meaning plainly. Alternate translation: [my power will be established]

Here, arm represents power or strength. If it would be helpful in your language, you could use an equivalent expression or state the meaning plainly. Alternate translation: [my power will also strengthen him]
