1 Kgs 2:32

וְהֵשִׁיב֩ יְהוָ֨ה אֶת־דָּמ֜וֹ עַל־רֹאשׁ֗וֹ אֲשֶׁ֣ר פָּגַ֣ע בִּשְׁנֵֽי־אֲ֠נָשִׁים צַדִּקִ֨ים וְטֹבִ֤ים מִמֶּ֨נּוּ֙ וַיַּהַרְגֵ֣ם בַּחֶ֔רֶב וְאָבִ֥י דָוִ֖ד לֹ֣א יָדָ֑ע אֶת־אַבְנֵ֤ר בֶּן־נֵר֙ שַׂר־צְבָ֣א יִשְׂרָאֵ֔ל וְאֶת־עֲמָשָׂ֥א בֶן־יֶ֖תֶר שַׂר־צְבָ֥א יְהוּדָֽה׃

The LORD will bring his bloodshed back upon his own head, for without the knowledge of my father David he struck down two men more righteous and better than he when he put to the sword Abner son of Ner, commander of Israel’s army, and Amasa son of Jether, commander of Judah’s army.
