OET interlinear PSA 106:31

uW Translation Notes:

Note 1 topic: figures-of-speech / activepassive

וַ⁠תֵּחָ֣שֶׁב ל֭⁠וֹ

(Some words not found in UHB: and,it_was_reckoned to=him/it to,righteousness to,a_generation and,a_generation until forever )

The expression It was counted to him 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: [People credited it to him]

Note 2 topic: figures-of-speech / abstractnouns

לִ⁠צְדָקָ֑ה

to,righteousness

If your language does not use an abstract noun for the idea of righteousness, you could express the same idea in another way. Alternate translation: [as a righteous deed]

Note 3 topic: figures-of-speech / idiom

לְ⁠דֹ֥ר וָ֝⁠דֹ֗ר

to,a_generation and,a_generation

The psalmist is using to generation and generation as a common expression of his culture to mean “throughout all generations” or “forever.” If this phrase does not have that meaning for your readers, you could use a comparable expression from your language that does have that meaning, or you could state the meaning plainly. Alternate translation: [and will be so throughout all generations]
