uW Translation Notes:

Note 1 topic: figures-of-speech / rquestion

לָ֤⁠מָּה אַכֶּ֨⁠כָּה֙ אַ֔רְצָ⁠ה וְ⁠אֵיךְ֙ אֶשָּׂ֣א פָנַ֔⁠י אֶל־יוֹאָ֖ב אָחִֽי⁠ךָ

(Some words not found in UHB: and,he_repeated again/more ʼAⱱnēr to=say to/towards ˊAsāh^ʼēl turn_aside to/for=yourself(m) from,after,me to/for=what will,I_strike_you towards=land and,how? show face_of,my to/towards Yōʼāⱱ/(Joab) your(ms)=brother/kindred )

Abner is using the question form for emphasis. If a speaker of your language would not use the question form for that purpose, you could translate this as a statement or as an exclamation. Alternate translation: [Do not make me strike you to the ground! Then I would not be able to lift my face to Joab, your brother.]

Note 2 topic: figures-of-speech / explicit

לָ֤⁠מָּה אַכֶּ֨⁠כָּה֙ אַ֔רְצָ⁠ה

(Some words not found in UHB: and,he_repeated again/more ʼAⱱnēr to=say to/towards ˊAsāh^ʼēl turn_aside to/for=yourself(m) from,after,me to/for=what will,I_strike_you towards=land and,how? show face_of,my to/towards Yōʼāⱱ/(Joab) your(ms)=brother/kindred )

By strike you to the ground, Abner means kill Asahel, causing him to fall to the ground dead. You could indicate this explicitly in your translation if that would be helpful to your readers. Alternate translation: [Why should I kill you, so that you fall to the ground dead]

Note 3 topic: translate-symaction

וְ⁠אֵיךְ֙ אֶשָּׂ֣א פָנַ֔⁠י אֶל־יוֹאָ֖ב אָחִֽי⁠ךָ

and,how? (Some words not found in UHB: and,he_repeated again/more ʼAⱱnēr to=say to/towards ˊAsāh^ʼēl turn_aside to/for=yourself(m) from,after,me to/for=what will,I_strike_you towards=land and,how? show face_of,my to/towards Yōʼāⱱ/(Joab) your(ms)=brother/kindred )

Abner failing to lift his face to look at Joab directly would be a symbolic action that would express shame for killing Asahel, a younger, less experienced warrior. If it would be helpful to your readers, you could explain the significance of this action. Alternate translation: [Then I would be too ashamed to look your brother Joab in the face]
