OET interlinear NUM 12:12

uW Translation Notes:

Note 1 topic: figures-of-speech / simile

אַל־נָ֥א תְהִ֖י כַּ⁠מֵּ֑ת אֲשֶׁ֤ר בְּ⁠צֵאת⁠וֹ֙ מֵ⁠רֶ֣חֶם אִמּ֔⁠וֹ וַ⁠יֵּאָכֵ֖ל חֲצִ֥י בְשָׂרֽ⁠וֹ

not now be like_(the),[person] which/who in=his/its=coming_out from,the_womb_of his/its=mother and,it_was_eaten half_of his_flesh_of,his

The point of this comparison is that just as one having died has decaying flesh, so Miriam has decaying flesh. If it would be helpful in your language, you could make this point explicitly. Alternate translation: [May her skin not be like the skin of the one having died, who, when he comes out from the womb of his mother, then half of his flesh was eaten]

Note 2 topic: figures-of-speech / idiom

בְּ⁠צֵאת⁠וֹ֙ מֵ⁠רֶ֣חֶם אִמּ֔⁠וֹ

in=his/its=coming_out from,the_womb_of his/its=mother

The author is using when he comes out from the womb of his mother as a common expression of his culture to mean “when he is born.” If this phrase does not have that meaning in your language, you could use a comparable expression from your language that does have that meaning, or you could state the meaning plainly. Alternate translation: [when he is born]

Note 3 topic: figures-of-speech / activepassive

וַ⁠יֵּאָכֵ֖ל חֲצִ֥י בְשָׂרֽ⁠וֹ

and,it_was_eaten half_of his_flesh_of,his

The expression was eaten is a passive verbal form. If your language would not use that form, you could express the idea in active form or in another way that is natural in your language. Alternate translation: [then half of his flesh has wasted away] or [then half of his flesh has rotted]
