OET interlinear NAH 1:3

uW Translation Notes:

Note 1 topic: figures-of-speech / idiom

אֶ֤רֶךְ אַפַּ֨יִם֙

slow_of (Some words not found in UHB: YHWH slow_of anger and,great_of ability and,certainly_(leave_unpunished) not he_will_leave_guilty_unpunished YHWH [is]_in,storm-wind and,in,storm its=road/course and,cloud[s] dust_of his_feet_of,his )

Here, long of nostrils is an idiom that means “slow to become angry.” If this phrase does not have that meaning in your language, you could use an idiom from your language that does have that meaning or state the meaning plainly. Alternate translation: [is patient] or [is slow to anger]

Note 2 topic: figures-of-speech / abstractnouns

ו⁠גדול־כֹּ֔חַ

and,great_of (Some words not found in UHB: YHWH slow_of anger and,great_of ability and,certainly_(leave_unpunished) not he_will_leave_guilty_unpunished YHWH [is]_in,storm-wind and,in,storm its=road/course and,cloud[s] dust_of his_feet_of,his )

If your language does not use an abstract noun for the idea of power, you could express the same idea in another way. Alternate translation: [and very strong] or [and very mighty]

Note 3 topic: figures-of-speech / reduplication

וְ⁠נַקֵּ֖ה לֹ֣א יְנַקֶּ֑ה

(Some words not found in UHB: YHWH slow_of anger and,great_of ability and,certainly_(leave_unpunished) not he_will_leave_guilty_unpunished YHWH [is]_in,storm-wind and,in,storm its=road/course and,cloud[s] dust_of his_feet_of,his )

The author is repeating the verb acquit in order to intensify the idea that it expresses. If your language can repeat words for intensification, it would be appropriate to do that here in your translation. If not, your language may have another way of expressing the emphasis. Alternate translation: [he will certainly not leave the guilty unpunished] or [he surely does not clear the guilty]
