OET interlinear ISA 63:5

uW Translation Notes:

Note 1 topic: figures-of-speech / metonymy

וַ⁠תּ֤וֹשַֽׁע לִ⁠י֙ זְרֹעִ֔⁠י

and,it_gave_victory to=me arm_of,my

Here, my arm represents Yahweh’s own strength. If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [So my own strength saved for me]

Note 2 topic: writing-pronouns

וַ⁠חֲמָתִ֖⁠י הִ֥יא סְמָכָֽתְ⁠נִי

and,rage_of,my she/it it,sustained_me

Yahweh is stating the pronoun it separately, even though the verb translated as it supported me already includes this meaning. He is doing that to emphasize that it was his own wrath, and not anyone else, that supported him when he found no other helper. If a speaker of your language would use an explicit pronoun for the same purpose, you may want to use that construction in your translation. If not, your language may have other ways of showing the meaning here. Alternate translation: [my anger itself supported me]
