II Samuel
II Samuel 2:12-28
The battle of Givon between the forces of David (Joab) and those of Ish-Boshet (Abner) — Jews fighting Jews — serves as a central biblical case study for civil war, ending with Abner's plea to halt the fratricidal killing.
וַיִּקְרָ֨א אַבְנֵ֜ר אֶל־יוֹאָ֗ב וַיֹּ֙אמֶר֙ הֲלָנֶ֙צַח֙ תֹּ֣אכַל חֶ֔רֶב הֲל֣וֹא יָדַ֔עְתָּה כִּי־מָרָ֥ה תִֽהְיֶ֖ה בָּאַֽחֲרוֹנָ֑ה וְעַד־מָתַי֙ לֹא־תֹאמַ֣ר לָעָ֔ם לָשׁ֖וּב מֵאַחֲרֵ֥י אֲחֵיהֶֽם׃ וַיֹּ֣אמֶר יוֹאָ֔ב חַ֚י הָאֱלֹהִ֔ים כִּ֥י לוּלֵ֖א דִּבַּ֑רְתָּ כִּ֣י אָ֤ז מֵהַבֹּ֙קֶר֙ נַעֲלָ֣ה הָעָ֔ם אִ֖ישׁ מֵאַחֲרֵ֥י אָחִֽיו׃ וַיִּתְקַ֤ע יוֹאָב֙ בַּשּׁוֹפָ֔ר וַיַּֽעַמְדוּ֙ כׇּל־הָעָ֔ם וְלֹא־יִרְדְּפ֥וּ ע֖וֹד אַחֲרֵ֣י יִשְׂרָאֵ֑ל וְלֹא־יָסְפ֥וּ ע֖וֹד לְהִלָּחֵֽם׃
Abner then called out to Joab, “Must the sword devour forever? You know how bitterly it’s going to end! How long will you delay ordering your troops to stop the pursuit of their own kindred?” And Joab replied, “As God lives, if you hadn’t spoken up, the troops would have given up the pursuit of their kindred only the next morning.” Joab then sounded the horn, and all the troops halted; they ceased their pursuit of Israel and stopped the fighting.
