OET interlinear ISA 48:8

uW Translation Notes:

Note 1 topic: grammar-connect-logic-result

כִּ֤י

that/for/because/then/when

The word translated as for indicates that what follows is a reason for what came before. Use a connector in your language that makes it clear that what follows is a reason for what came before. Alternate translation: [since]

Note 2 topic: writing-poetry

כִּ֤י יָדַ֨עְתִּי֙ בָּג֣וֹד תִּבְגּ֔וֹד

(Some words not found in UHB: also/yet not you(ms)_paid_attention also/yet not known also/yet from,then not open ear_of,your that/for/because/then/when I_know treacherously deal_treacherously and,a_rebel from_[the],womb called to/for=you(fs) )

Isaiah is using a construction in which a verb and its object come from the same root. You may be able to use the same construction in your language to express the meaning here. Alternatively, your language may have another way of saying this. Alternate translation: [for I knew that you would surely betray me]

Note 3 topic: figures-of-speech / idiom

מִ⁠בֶּ֖טֶן

from_[the],womb

Yahweh is using from the womb as a common expression of the culture to mean “from the time you were born.” 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: [from the time you were born]

Note 4 topic: figures-of-speech / activepassive

וּ⁠פֹשֵׁ֥עַ מִ⁠בֶּ֖טֶן קֹ֥רָא לָֽ⁠ךְ

and,a_rebel from_[the],womb called to/for=you(fs)

The expression was called 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: [and from the womb, I called you “rebelling one”]
