OET interlinear GEN 39:9

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

אֵינֶ֨⁠נּוּ גָד֜וֹל בַּ⁠בַּ֣יִת הַ⁠זֶּה֮ מִמֶּ⁠נִּי֒

not,he greater (Some words not found in UHB: not,he greater in,household the=this more,than_me and=not withheld from,me anything that/for/because/then/when if ,you because, you his/its=wife/woman and,how? do the,evil the=big/large/great(fs) (the),this and,I_will_sin to,God )

By saying He is not greater than me in this house, Joseph means that Potiphar still had more authority than Joseph, but he had given Joseph authority to act in his place over everything in his household. You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [As a result, even he does not exercise more authority in his household than I do]

Note 2 topic: figures-of-speech / litotes

וְ⁠לֹֽא־חָשַׂ֤ךְ מִמֶּ֨⁠נִּי֙ מְא֔וּמָה כִּ֥י אִם־אוֹתָ֖⁠ךְ בַּ⁠אֲשֶׁ֣ר אַתְּ־אִשְׁתּ֑⁠וֹ

and=not (Some words not found in UHB: not,he greater in,household the=this more,than_me and=not withheld from,me anything that/for/because/then/when if ,you because, you his/its=wife/woman and,how? do the,evil the=big/large/great(fs) (the),this and,I_will_sin to,God )

Joseph is using a figure of speech here that emphasizes a positive meaning by using a negative word, not, together with a mild expression that is the opposite of the intended meaning. If it would be helpful in your language, you could emphasize the positive meaning in a strong way. The phrase has not withheld emphasizes the freedom that Potiphar had given Joseph. Some languages must translate this in a way that does not use a negative word such as not. Alternate translation: [and he has given me freedom with everything in his household, except you, of course, because you are his wife]

Note 3 topic: figures-of-speech / rquestion

וְ⁠אֵ֨יךְ אֶֽעֱשֶׂ֜ה הָ⁠רָעָ֤ה הַ⁠גְּדֹלָה֙ הַ⁠זֹּ֔את וְ⁠חָטָ֖אתִי לֵֽ⁠אלֹהִֽים

and,how? (Some words not found in UHB: not,he greater in,household the=this more,than_me and=not withheld from,me anything that/for/because/then/when if ,you because, you his/its=wife/woman and,how? do the,evil the=big/large/great(fs) (the),this and,I_will_sin to,God )

Joseph uses this rhetorical question to emphasize why he will not do what Potiphar’s wife wants. Alternate translation: [So I refuse to do such an evil thing, which would be a terrible sin against God!]
